Read your three priorities in order and watch which product each one removes. Convenience first does not select the expensive answer - on its own it selects the cheapest thing in the range, because a 12ml hanging bottle at ₹449 asks nothing of you between purchase and refill. It is adjustable intensity in second place that eliminates it, since a wick has no adjustment of any kind. And cost in third place is what permits what follows: SOSA Safar at ₹3,999, or ₹4,499 for the hotel-inspired trios, with three speed settings and an auto shut-off at one, two or three hours. This page is the deliberate mirror of the control-first one.
Quick answers — read this first
Should I buy spray, hanging perfume or waterless diffusion if my priorities are convenience first, adjustable intensity second and cost third? SOSA Safar, at ₹3,999 for the SOSA scent trios or ₹4,499 for the hotel-inspired ones. Convenience first removes the spray, which asks for an action at the start of every journey. Adjustable intensity second removes the hanging unit, whose level is fixed by its own exposed surface with no way to change it. Cost third is what makes the remaining answer affordable to consider.

Would convenience first on its own not point at the cheapest format? Yes, and that is the most useful thing on this page. A hanging car perfume at ₹449 to ₹509 is the lowest-effort product in the range: hook it once, refill it at ₹399 to ₹449 when it is dry, and nothing else ever. If adjustable intensity were your third priority rather than your second, that is what you should buy and you would save several thousand rupees doing it.

What does cost third actually permit? It permits the real total rather than the headline: ₹3,999 or ₹4,499 for the device, plus waterless refills at ₹1,049 per 100 gm or ₹1,849 per 300 gm. Cost third does not mean cost ignored, and the honest comparison is against ₹449 to ₹509 for a 12ml unit plus ₹399 to ₹449 per 15ml refill. A true cost per millilitre across the two is not available, because one is sold by volume and the other by weight.
The short answer
Short answer: Buy SOSA Safar - ₹3,999 for the SOSA scent trios, ₹4,499 for the hotel-inspired trios. Convenience first eliminates the spray, whose control is excellent and must be exercised in person at the start of every drive. Adjustable intensity second eliminates the hanging unit, which is the most convenient product in the range and has no adjustment at all - one fixed level, no raise, no lower, no pause. That leaves the only format where convenience and adjustment coexist: three speed settings, an auto shut-off timer at one, two or three hours, and up to ten hours continuous or thirty hours intermittent per charge, so nothing is required of you per journey. Cost third permits the real figure, which is the device plus refills at ₹1,049 per 100 gm or ₹1,849 per 300 gm.
The pick: SOSA Safar at ₹3,999 with one 100 gm waterless refill at ₹1,049 rather than the 300 gm tier at ₹1,849 until the scent has earned a month. Check the fifteen-scent list first: it contains no oud and no lavender.
Next step: run the lowest speed with the one-hour timer for a week before touching anything, and charge it alongside a fixed weekly routine. Then read this page's mirror - control first, convenience second, longevity third - which uses nearly the same words and lands on a ₹449 bottle. Or send SOSA your priority order and we will tell you what it selects.

The device, its oil, and what a different ordering would have bought - tap to see each
Straight answer
My priorities are convenience first, adjustable intensity second and cost third. Should I buy a car perfume spray, a hanging car perfume or waterless diffusion?
SOSA Safar - and I want to walk the elimination in order, because the most interesting thing about your list is that its first item on its own would have sent you to the cheapest product we make. Step one: convenience first removes the spray. This is clean. The spray form of a 12ml car perfume - the same composition and the same price as the hanging version, listed on one page as “Spray (Strong scent-throw)” and “Hanging (Mild scent-throw)”, with a “50 ML Car Perfume Spray” at ₹1,499 - offers the finest intensity control in the range and charges you an action for it. A press at the start of every drive, every drive, forever, and nothing at all on the journeys you forget. The reader who ranks control above convenience accepts that trade happily and buys a ₹449 bottle. You put convenience first, so you do not. Step two, and this is where the page earns its place: convenience on its own would buy you the hanging unit, not the device. I want to be emphatic about this because the industry would rather you did not notice it. A hanging car perfume is the lowest-effort fragrance product in this entire range. You unwrap it, hook it, and from that moment until the bottle is dry there is nothing to press, nothing to charge, no cable, no setting, no decision and nothing to reorder on a schedule. ₹449 for jasmine through ₹509 for oud, and then a 15ml refill at ₹399 to ₹449 which holds more oil than the 12ml unit it refills and costs less than it. If adjustable intensity were your third priority rather than your second, the honest recommendation on this page would be a ₹449 bottle and you would keep several thousand rupees. Step three: adjustable intensity in second place is what eliminates it, and it eliminates it absolutely rather than marginally. A hanging unit does not have a weak adjustment. It has none. Its output is a function of its own exposed liquid surface and the temperature of the cabin, and there is no mechanism on the product by which a human being can raise it, lower it or pause it. The only interventions available are opening a window, moving the bottle further away, or taking it out of the vehicle altogether. For a reader who wants adjustment as their second priority, that is not a compromise to be weighed - it is a requirement the product cannot meet at any price. So what is left is the format where convenience and adjustment coexist, and it is the only one. Safar is ₹3,999 for the SOSA scent trios and ₹4,499 for the hotel-inspired trios. Three speed settings, so intensity is a choice among defined positions. An auto shut-off timer at one, two or three hours, so the end of the exposure is also chosen rather than endured. Up to ten hours continuous or thirty hours intermittent per charge on 2000 mAh over Type-C, which is what makes it convenient in your sense: the setting you choose on Monday is still being delivered on Thursday without you doing anything at the start of a drive. It is fully cordless, about 9 cm, sits in a cup-holder, and diffuses pure undiluted oil cold with no water and no heat. Now cost, which you ranked third, and third is not nowhere. Here is the real figure rather than the headline. ₹3,999 or ₹4,499 for the device, and then waterless refills at ₹1,049 per 100 gm or ₹1,849 per 300 gm. Against that, the passive answer is ₹449 to ₹509 once and ₹399 to ₹449 per 15ml refill thereafter. I cannot give you a cost per millilitre across the two, and I want to explain why rather than fudging it: the car perfumes are sold by volume and the waterless refills by weight, and the Safar ships with a 20ml bottle, so the published figures do not support a conversion. What is comparable is purchase price, refill price, and how often each is actually consumed - and the third of those is not published for any format, which is why the method at the end of this page asks you to date your own refill. Two honest limits before you pay. SOSA publishes no coverage figure for Safar in any unit, so nobody can tell you it is specified for your cabin and this page does not. And the waterless refill range runs to fifteen scents with no oud and no lavender among them - both exist in the 12ml format, at ₹509 and ₹479 - so confirm your scent exists before the money moves.
Buy SOSA Safar at ₹3,999, or ₹4,499 for the hotel-inspired trios. Convenience first removes the spray, which needs an action every journey. Convenience alone would have bought the ₹449 hanging bottle - it is adjustable intensity in second place that removes it, because a wick has no adjustment at all. Cost third permits the real total: the device plus refills at ₹1,049 or ₹1,849. Flip: move adjustment to third and the honest answer is a 12ml unit at ₹449 to ₹509 with a ₹399 refill.
SOSA Safar at ₹3,999, or ₹4,499 for the hotel-inspired trios - three speed settings, an auto shut-off timer at one, two or three hours, up to ten hours continuous or thirty hours intermittent per charge, cordless and cup-holder sized. Start on the lowest speed and leave it there for a week.

What each priority eliminates

The two cards below are the formats your ranking removes. One is removed by your first priority and one by your second, and the second removal is the expensive one - so it is worth being sure of it.

What convenience alone would have bought
SOSA Oud Car Perfume
The lowest-effort product in the range. Hook it once and there is nothing to press, charge, plug in, set or reorder until it is dry, at which point a 15ml refill at ₹399 to ₹449 holds more oil than the 12ml unit it refills and costs less. ₹449 for jasmine, ₹509 for oud. Its only failing against your list is that it has no adjustment whatsoever - not a mild one, none - so a passenger who wants it reduced cannot be answered except by a window or by removing the bottle.
₹509 for 12ml · oud, in the hanging form
Selected - the one format where convenience and adjustment coexist
SOSA Safar Waterless Car Perfume Diffuser
Three speed settings and an auto shut-off timer at one, two or three hours, so both the level and its duration are chosen rather than inherited. Up to ten hours continuous or thirty hours intermittent per charge on 2000 mAh over Type-C, cordless, about 9 cm, cup-holder sized, diffusing pure undiluted oil cold with no water and no heat. Nothing is required of you at the start of a journey, which is the convenience you asked for, and the level can still be moved, which is the adjustment.
₹3,999 · ₹4,499 for the hotel-inspired trios
The figure that cost third should actually be applied to
SOSA Waterless Nebuliser Refills
Pure undiluted oil shared with the SOSA Vaayu: eight SOSA scents at ₹1,049 per 100 gm and ₹1,849 per 300 gm, and seven hotel-inspired variants at ₹1,099 and ₹1,899. Fifteen scents, with no oud and no lavender. This is where a device's real cost lives, and it is also where the comparison with the passive format becomes honest rather than rhetorical - ₹399 to ₹449 per 15ml against these figures, with no cost per millilitre available across the two because one range is sold by volume and the other by weight. Buy the 100 gm tier first.

The five things that decide this

Five variables sit under a priority-ordered question. The second is the one that costs you several thousand rupees, the third is what cost-third actually commits you to, and the fifth is the only hard stop.

1
Which convenience you meant
Nothing to operate and nothing to remember are two different things
Convenience is the most overloaded word in this category and your second priority is what disambiguates it. One meaning is nothing to operate - no device, no settings, no charging, no interface at all. That meaning points at a wick and at ₹449. The other meaning is nothing to remember, but still controllable - the release happens without you while the level stays yours. That meaning points at a powered format. By putting adjustable intensity second, you have told me you meant the second kind, and that single clarification is worth more than any specification comparison. The page that splits the word properly is the best thing in this cluster to read beside this one.
Test: do you want no interface, or no routine? The first is a bottle and the second is a device, and they differ by several thousand rupees.
2
Why adjustment second is the expensive decision
Convenience first alone would have bought the cheapest thing in the range
I would rather you understood where your money is going than simply spent it. The spray was removed by convenience and the hanging unit was removed by adjustment, and the hanging unit is ₹449 to ₹509. So the roughly three-and-a-half thousand rupees of difference is being paid for adjustment and for nothing else. That is a reasonable purchase if the adjustment gets used, and an expensive ornament if it does not - and there is a simple way to find out which. Count the journeys in the last month where you would genuinely have changed the level if you could. If the number is low, your second priority may be aspirational. The counting test page is written around exactly this and it is a refuse-the-sale page.

3
What cost third commits you to, stated honestly
Third is not nowhere, and the real figure includes the oil
Ranking cost last licenses the purchase; it does not make the purchase free, and the number worth knowing is not the one on the box. ₹3,999 or ₹4,499 once, then ₹1,049 per 100 gm or ₹1,849 per 300 gm for as long as you own it. The passive alternative is ₹449 to ₹509 once and ₹399 to ₹449 per 15ml thereafter. A cost per millilitre across those two is not available and I will not manufacture one - the car perfumes are sold by volume, the waterless refills by weight, and the Safar ships with a 20ml bottle, so the published figures do not support the conversion. What is comparable is purchase price, refill price and consumption frequency, and the third is unpublished for every format. The refill-cost page and the one-year page work this through properly.
Rule: put the refill price in the comparison or the comparison is wrong. The device is the cheap part of a long relationship.
4
The chore convenience quietly introduces
A charging habit replaces a per-journey habit, and it fails worse
Convenience first means you should know exactly what the device still asks of you. 2000 mAh over Type-C, up to ten hours continuous or thirty hours intermittent per charge - generous, periodic, and not optional. The failure mode is worse than the one you escaped. A forgotten press costs one journey; a flat battery costs a week, usually discovered on the morning you had passengers, which is the moment your second priority mattered most. The mitigations are dull and they work: charge it on the same day as a fixed weekly routine, and keep one 12ml bottle in the door pocket as a fallback. The charge-failure page is a refuse-the-sale page for readers whose forgetfulness is structural, and the forgetting page argues the other side.
Habit: pair the charge with something fixed and weekly. Convenience you have to remember is not convenience.
5
Whether your scent exists in the format
Fifteen waterless scents, and neither oud nor lavender among them
This is the only hard stop and it outranks every argument above, because it is about existence rather than performance. The waterless refill range has fifteen scents across two tiers and it contains no oud and no lavender. Both exist in the 12ml car perfume range - oud ₹509 with a 15ml refill at ₹449, lavender ₹479 with a refill at ₹429. So if the fragrance you want adjusted is oud, no speed setting helps, and the honest answer becomes the passive bottle with the adjustment you wanted and cannot have. Check before you pay. The availability matrix sets every scent family against every format, and the refill-availability page makes the long-term case.
Order of operations: confirm the scent, then choose the format, then compare the features. Availability beats specification every time.
The SOSA principle
Convenience first does not buy a machine. On its own it buys the cheapest bottle in the range. It is the requirement in second place that decides how much the first one costs you.
Which is why a priority list should be written in order and then read twice - the second item is nearly always where the money actually goes.
The format where both priorities survive: SOSA Safar, ₹3,999 and ₹4,499 for the hotel-inspired trios - three speed settings, an auto shut-off at one, two or three hours, ten hours continuous or thirty intermittent per charge, cordless and cup-holder sized.

What would reverse this answer

Move one item in your list and the purchase moves with it, often by several thousand rupees. This is the clearest demonstration in the cluster that a ranking is a specification.

The honest reversal
One item moved in the list, and the purchase moves by thousands
The priority order What it selects, and exactly why
Convenience, then adjustable intensity, then cost - as written
Safar, which is this page. The only format where the release needs nothing from you per journey and the level can still be moved. Three speeds, an auto shut-off at one, two or three hours, ten hours continuous per charge. ₹3,999, or ₹4,499 for the hotel-inspired trios. View ₹3,999 →
Convenience, then cost, then adjustable intensity
The hanging unit, and you save most of the money. With adjustment demoted, the lowest-effort product in the range becomes available: hook it once, refill at ₹399 to ₹449 when dry, and never think about it. ₹449 to ₹509. This is the single most common correct answer in this family. View ₹509 →
Adjustable intensity, then convenience, then cost
The spray, and this is the mirror page. Putting control above convenience means you want the decision in your hand during the journey rather than configured before it, and no machine offers that. ₹449 to ₹549, and longevity becomes a measurement rather than a criterion. View ₹509 →
Cost first, whatever follows it
Then the answer is a 12ml unit at ₹449 and a 15ml refill at ₹399, and nothing in this family changes that. Cost first is the one ordering that has a single answer regardless of what comes second or third, because the cheapest format is also the lowest-effort one and the only thing it fails on is adjustment. What this page cannot give you is a cost per millilitre across the two systems: the car perfumes are sold by volume and the waterless refills by weight, so the published figures do not support a conversion and none is offered.

Two neighbours are worth a line. The page that asks whether ₹3,999 upfront is worth it for automation and adjustable intensity is the cost family's version of this question. The most-economical-over-a-year page brings all three cost lines together with the unpublished one marked honestly. And the list of things SOSA establishes before recommending anything is where this cluster ends.

Where the real cost lives: SOSA Waterless Nebuliser Refills, ₹1,049 per 100 gm against ₹1,849 per 300 gm - fifteen scents with no oud and no lavender. Cost ranked third still deserves the honest total rather than the headline.
Lowest speed, shortest timer, charged on a fixed day
Safar is ₹3,999, or ₹4,499 for the hotel-inspired trios, with refills at ₹1,049 and ₹1,849. Send us your three priorities in order and we will tell you what that order selects - including the version where the honest answer is a ₹449 bottle and a ₹399 refill.
See SOSA Safar Send SOSA your usage
Almost nobody who ranks convenience first actually needs a machine. What makes the difference is the item in second place, and in your list it is adjustment - which is the one thing the cheapest format in the range cannot do at all, at any price, in any cabin.

How to run it so the convenience survives

Everything below is free, and all of it is about protecting the thing you ranked first, which is the part new owners most often undermine in the first week.

Four habits that keep a powered format convenient rather than fiddly
Step What to do Why it matters Where it applies
SOSA Safar Waterless Car Perfume Diffuser Choose the lowest speed and then stop adjusting You ranked convenience first, and a device you fiddle with daily has lost you the thing you paid for. Three positions means there is no reason to begin at the second. Set the lowest, leave it a week, and move it only if somebody who has just got in says it is too faint ₹3,999 · three speeds

SOSA Safar Waterless Car Perfume Diffuser Set the timer once and let it govern the journey The auto shut-off at one, two or three hours is the part of the configuration that does the most work for the least attention, because it ends an exposure you would otherwise have to notice and act on. Start at one hour and extend it only if the cabin is genuinely empty before you arrive ₹3,999 · one, two or three hours

SOSA Jasmine Car Perfume Keep a 12ml bottle in the door pocket Ten hours continuous or thirty intermittent per charge is generous, and a flat battery still means a week of nothing at the worst possible moment.

SOSA Waterless Nebuliser Refills Date the refill and write the setting beside the date SOSA publishes no duration figure for a 20ml bottle, a 100 gm refill or any speed setting, so no honest page will give you one.

SOSA Safar is ₹3,999 for the SOSA scent trios and ₹4,499 for the hotel-inspired trios, with waterless refills shared with the SOSA Vaayu at ₹1,049 and ₹1,849 for the SOSA scents and ₹1,099 and ₹1,899 for the rest. The 12ml car perfumes remain at ₹449 to ₹549 in two forms of release at one price - “Spray (Strong scent-throw)” and “Hanging (Mild scent-throw)” - with a “50 ML Car Perfume Spray” at ₹1,499 and 15ml hanging refills at ₹399 to ₹449. No coverage figure is published for Safar and none is given here. A car fragrance is a fragrance: it does not mask the smell of damp carpet or a tired cabin filter, and SOSA makes no claim about mood, alertness, wellbeing, air quality or driving. Send us your priority order and we will tell you what it selects.

What to buy, and in what order

One Safar at ₹3,999, one 100 gm waterless refill at ₹1,049, and one 12ml bottle for the door pocket - jasmine at ₹449 is the cheapest, vetiver khus at ₹509 the driest in a hot cabin, sandalwood at ₹479 the quietest of the heavier scents if the fallback ever has to carry a full vehicle. What not to buy yet: the 300 gm refill at ₹1,849, which commits you to a scent you have not lived with for a month; the ₹4,499 trio, unless one of those seven hotel-inspired variants is specifically the scent you want; and a second source anywhere in the cabin, which gives you a level nobody set. And the honest alternative, if the counting test goes badly: oud at ₹509 or any 12ml unit in the hanging form with a 15ml refill at ₹399 to ₹449, which is what convenience-first buys the moment adjustment stops being your second priority.

The fallback worth owning: SOSA Jasmine car perfume, ₹449 for 12ml in either form of release at the same price - the cheapest insurance against a flat battery, and it asks nothing of you until the day you need it.

A note from Sonal

I publish this page and its mirror as a pair deliberately, and if you read only one of them you have missed the point of both. They are built from almost the same three words. One lands on a bottle that costs a few hundred rupees and the other on a machine that costs several thousand, and the only thing that differs is the sequence. I cannot think of a cleaner demonstration that the order of a list is the whole of its content.

What I would most like you to notice about your own list is that convenience first, taken alone, is an argument for the cheapest thing we sell. A hanging bottle asks nothing of anybody. So the money you are about to spend is being spent entirely on the second item, and that is worth a moment's honesty: count the journeys last month where you would genuinely have changed the level if you could have. If the honest number is two, buy the ₹449 bottle and a refill and write to me in a year. I have written the counting test out here because I would rather lose the sale than have the settings go unused.

And check the refill list before you pay. There is no oud in the waterless range and no lavender either, and I am not going to tell you that mahogany is a dark enough woody to stand in for oud, because you would notice within a week. If one of those two is the scent you want adjusted, buy the 12ml bottle and accept the fixed level - availability is not something a feature list can argue with. Write to me with your three priorities in order and the scent you have in mind and I will tell you which of these two pages is yours.

Frequently asked questions

Spray, hanging perfume or waterless diffusion if my priorities are convenience first, adjustable intensity second and cost third?
SOSA Safar, at ₹3,999 or ₹4,499 for the hotel-inspired trios. Convenience first removes the spray, which needs an action at the start of every drive. Adjustable intensity second removes the hanging unit, which is the most convenient product in the range and has no adjustment at all. Cost third permits the real total: the device plus refills at ₹1,049 per 100 gm or ₹1,849 per 300 gm.
If convenience is my first priority, why is the answer not the cheapest product?
On its own it would be. A hanging car perfume at ₹449 to ₹509 is the lowest-effort product in the range: hook it once and do nothing until a 15ml refill at ₹399 to ₹449 is due. What removes it is your second priority, because a wick has no adjustment of any kind - not a weak one, none. The money is being spent on adjustment rather than on convenience.
How do I know whether adjustable intensity is worth the extra money?
Count the journeys in the last month where you would genuinely have changed the level if you could have. If the honest number is two or three, the settings will be admired rather than used, and a ₹449 to ₹509 hanging unit with a ₹399 to ₹449 refill is the better purchase. If somebody is regularly asking for it to be turned down, the adjustment pays for itself.
What is the real cost of the waterless route, not just the purchase price?
₹3,999 or ₹4,499 for the device, then waterless refills at ₹1,049 per 100 gm or ₹1,849 per 300 gm for as long as you own it. The passive alternative is ₹449 to ₹509 once and ₹399 to ₹449 per 15ml refill. A cost per millilitre across the two is not available, because the car perfumes are sold by volume and the waterless refills by weight.
Does convenience mean the same thing for every reader?
No, and the ambiguity decides this purchase. One meaning is nothing to operate - no device, no settings, no charging - which points at a hanging bottle. The other is nothing to remember but still controllable, which points at a powered format. Your second priority is what disambiguates it, and in this ordering you have asked for the second kind.
What convenience-first buys without the second priority: SOSA Oud car perfume, ₹509 for 12ml in the hanging form at the same price as the spray - the lowest-effort product in the range, with a 15ml refill at ₹449 that holds more oil than the unit.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. The reasoning here - occupied cabin hours, evaporation while parked, airflow, exposure time and olfactory adaptation - applies to any brand; the products and prices are SOSA’s. Where SOSA publishes no figure, this guide says so and gives a way to measure it in your own vehicle rather than quoting a number.

Facts verified 3 October 2026 against the live SOSA product pages: SOSA car perfume is sold as one 12ml product in two formats at the SAME price, listed on the product page as "Spray (Strong scent-throw)" or "Hanging (Mild scent-throw)", with a "50 ML Car Perfume Spray" at ₹1,499. The nine scents are Jasmine ₹449, Lavender ₹479, Sandalwood ₹479, Icy Mint ₹489, Lemon ₹499, Vetiver khus ₹509, Sea Breeze ₹509, Oud ₹509 and Mysore Orange Blossom ₹549, the last of which is spray only. Car Hanging Freshener Refills are 15ml at ₹399 to ₹449 in eight scents - a larger bottle than the 12ml unit they refill. The SOSA Safar waterless car and travel diffuser is ₹3,999 for the SOSA scent trios and ₹4,499 for the hotel-inspired trios, with three speed settings, an auto shut-off timer at one, two or three hours, up to ten hours continuous or thirty hours intermittent per charge, a 2000 mAh battery, Type-C charging, a body of about 9 cm that fits a cup-holder, and a 20ml bottle in the box; it diffuses pure undiluted oil cold, with no water and no heat, and the product page states "Aroma only - does not humidify", which is not a claim that it dries a cabin or corrects damp. SOSA publishes NO coverage figure for Safar - no square feet, no cubic metres and no seat count - so no page here sizes it to a vehicle. Waterless Nebuliser Refills are shared with the SOSA Vaayu at ₹1,049 per 100 gm and ₹1,849 per 300 gm for the SOSA scents, and ₹1,099 and ₹1,899 for the hotel-inspired scents; that range contains no oud and no lavender, while the 12ml range contains both. The car perfumes are sold by volume and the waterless refills by weight, so a cost per millilitre across the two systems is not available from the published figures and none is given here. SOSA publishes no duration figure for a 12ml unit, a 20ml Safar bottle or any speed setting. No SOSA product removes an odour at its source: food, damp and smoke in a cabin are cleaning and ventilation problems, and fragrance sits on top of whatever is already there. SOSA makes no claim about mood, alertness, concentration, wellbeing or driving, and no claim about air quality or purification. After-sales terms, bulk arrangements and delivery commitments are confirmed with SOSA directly; free shipping above ₹499 is the only logistics fact stated. The hotel-inspired scent names are SOSA’s own interpretations and catalogue variant names; SOSA is independent and not affiliated with any hotel or brand named for reference.
