Founder Diaries · Optical Retail · The Eyewear Section
If the optical section is genuinely separate — its own room, a door that is normally closed — a warmer register is defensible. In the SOSA reed range that means Fresh Brew at ₹849 / ₹1,349 and nothing else: there is no oud, no musk and no amber reed in the range.
If it shares air with reception, run the same scent one half-step up. One extra reed in the optical bottle, or the same machine setting sited on the retail side. A half-step of the same composition is the version of "warmer" that survives an open floor plan.
What this page will not claim: no fragrance here affects how long anyone browses, what they buy or how anyone feels, and nothing here is medical or safety advice. Some people are sensitive to airborne fragrance, which is why the clinical pathway stays fragrance-free.

Count the things that would stop air: a door that is normally closed, a lobby with two doors, a change of level, a full-height partition with the AC supply on one side and the return on the other. An archway is not a boundary. A half-height display run is not a boundary. A change of flooring is not a boundary — it is a change of flooring, and air walks over it without noticing. If you counted zero, your optical section and your clinical corridor are one air path, and the warmer-register conversation is closed for your building. If you counted one real boundary, you have a retail room and the rest of this page is written for you.

SOSA range, specifications and prices used in this guide (verified August 2026): Vaayu ₹11,999 — waterless cold-air nebulisation of undiluted fragrance oil; no water, no heat, no added humidity, no white mineral dust. Coverage up to 1000 m³, about 2,000–3,000 sq ft. 400ml refillable tank lasting roughly 90+ days at a mid setting. Bluetooth app plus onboard controls, 1h / 4h / 8h / 24h run windows, day selection, adjustable intensity, auto-stop and key-lock. Under 38 dB. DC 12V / 1A, 5W. Freestanding or wall / HVAC mount. CE, RoHS and SGS certified. SOSA does not currently sell a separate Vaayu cold-air refill oil; the 400ml supplied in the box is the fragrance available at the time of writing, so a practice planning continuous or multi-site use should confirm current refill availability with SOSA before committing. The water-based Hotel Collection is made for ultrasonic machines and must not be used in a Vaayu. Other machines: Boond 300ml ₹899 (~150 sq ft, ultrasonic) · Sukoon 500ml ₹1,899 (270–320 sq ft, 16–18 hours on low, remote and steady/2H/4H timers, three 15ml fragrances included, ultrasonic) · Megh 6L ₹3,499 (~215 sq ft — a runtime and humidity machine that covers less than a Sukoon, never a coverage upgrade) · Safar ₹3,999 (waterless cold diffusion, cordless, 20ml, about 6.9cm, three speeds, 1/2/3-hour auto-off — sold as a car and travel diffuser, personal-scale only; SOSA publishes no coverage figure for it) · Aangan ₹25,999 (HVAC nebulising, ~8,000–10,000 sq ft) · Meenar ₹38,500 (commercial HVAC, 12,000–18,000 sq ft). Water-based Hotel Collection for ultrasonic machines: 15ml ₹299 · 100ml ₹999 · 300ml ₹1,799 · pack of seven ₹1,799; scents are inspired by the atmosphere of well-known hotels — SOSA is an independent Indian brand and is not affiliated with, endorsed by or supplying any hotel group. Reed diffusers ₹749–₹1,349 (50ml 6–8 weeks, 130ml 14–18 weeks, six fibre reeds, no 100ml size; replacement reeds are not sold separately). Reed oil cannot be used in an ultrasonic machine and Hotel Collection oil cannot be used in reeds. SOSA sells no room spray or home spray — every SOSA spray is a car perfume. Nothing in this guide is medical, clinical or safety advice. A fragrance diffuser adds a scent to the air. It does not clean, purify, filter, sanitise or disinfect air, does not remove or neutralise disinfectant, damp or occupancy smells, and has no effect on comfort, anxiety, waiting time, recovery or any clinical outcome. Some people are sensitive to airborne fragrance, which is why this guide recommends that examination rooms, diagnostic areas, consultation cabins, procedure suites and post-operative areas remain fragrance-free, that a fragrance-free seating option always exist, and that a diffuser is never mounted into shared HVAC in a clinical building. Decisions about clinical policy, ventilation standards, infection control and patient suitability rest entirely with the practice and its clinicians. A persistent stale, damp or disinfectant smell is a ventilation, moisture or cleaning problem — SOSA sells no dehumidifier and no air purifier, and fragrance should never be used to cover one. Coverage, runtime and longevity figures are manufacturer specifications and typical ranges, not guarantees, and vary with room volume, ceiling height, air exchange, occupancy and season. SOSA publishes no commercial or bulk pricing, no corporate account, no annual maintenance contract, no installation service, no stated warranty term and no multi-location programme; warranty length, spare parts, servicing and app platform availability are unconfirmed, and larger or multi-site enquiries should go through the contact page before any commitment.

The optical and eyewear section is the one part of an eye clinic that is genuinely a shop, and the only zone in this subject where I will argue for a warmer, more deliberate scent than the arrival area gets. But the permission is conditional, and the condition is architectural rather than aesthetic: the air leaving your eyewear section must not arrive in the clinical corridor. If it does — and in a great many Indian clinics the optical display is simply a wall of the waiting room — your eyewear section smells exactly like your reception, at exactly the same level. The boundary the rest of this cluster rests on holds here too: reception, waiting and optical retail are hospitality and retail space; diagnostics, examination rooms, consultation cabins, the procedure suite and any post-operative area are clinical space, and nothing I sell goes into them.
Quick answers — read this first
Answer the floor plan before you answer the fragrance. Walk from the middle of your eyewear display to the mouth of the consultation corridor. If there is no door, no lobby and no change of level between them, they are one air path and one scented zone, and the warmer register is off the table.If the optical section is genuinely separate — its own room, a door that is normally closed — a warmer register is defensible. In the SOSA reed range that means Fresh Brew at ₹849 / ₹1,349 and nothing else: there is no oud, no musk and no amber reed in the range.
If it shares air with reception, run the same scent one half-step up. One extra reed in the optical bottle, or the same machine setting sited on the retail side. A half-step of the same composition is the version of "warmer" that survives an open floor plan.
What this page will not claim: no fragrance here affects how long anyone browses, what they buy or how anyone feels, and nothing here is medical or safety advice. Some people are sensitive to airborne fragrance, which is why the clinical pathway stays fragrance-free.
The short answer
Short answer: dry and low if the eyewear section shares air with reception and the corridor; a half-step warmer if it has its own air. Behind a real boundary that is Fresh Brew ₹849; in an open plan it is Mountain Breeze ₹849 at one reed more than reception, or a Sukoon ₹1,899 on the retail side of the room.
Why it is a floor-plan question: fragrance does not respect the label you have given a zone. It follows the air, and in a clinic the air very often runs from the optical wall straight down the corridor the practice most wants to keep clear. Nothing you choose to buy changes that.

Straight answer
What should the eyewear section inside an eye clinic smell like?
1. Of the same thing as reception, unless the optical section has its own air. That is the default and the correct answer for most Indian eye clinics, where the frames sit along one wall of the waiting room. A zone is only a zone when the air agrees with the floor plan; if yours does not, you have one space with two names, and one space takes one scent.
2. If it does have its own air, a half-step warmer is defensible — and only a half-step. The optical section is retail: people stand, handle frames, look in mirrors and leave. That justifies a register with a little more body. It does not justify a showroom level, and it never justifies anything that could travel.
3. In the SOSA reed range, "warmer" means Fresh Brew and nothing else. Coorg coffee over Kerala vanilla, at 9.5 on our own internal strength scale at six reeds — a position on SOSA's scale, not an industry standard and not a concentration. There is no oud, no musk-forward composition and no amber in the reed line.
4. Size to the optical zone, not to the clinic. Most optical bays measure 120–320 sq ft. Under about 150 that is a reed bottle; from roughly 150 to 320 a Sukoon at ₹1,899; a Vaayu at ₹11,999 only past 320 sq ft of connected volume.
5. Put the source at the far end of the retail run from the corridor. Not on the dispensing table, not near the fitting mirror, not on the counter where an optometrist works all day. If the optical section has a street entrance, the source belongs between the frames and that entrance.
6. Nothing here is clinical advice. Ventilation, cleaning protocol, infection control and patient suitability rest with you and your clinicians. A practice that reads this page and decides its optical section gets nothing has read it correctly.
Everything SOSA makes is composed and made in small batches in Pune, and a portion of every order supports girl-child education through Nanhi Kali.

TL;DR: walk from the frames to the consultation corridor. No door between them means one zone and one scent — Mountain Breeze from ₹849, one reed higher in optical at most. A real boundary means a half-step warmer with Fresh Brew ₹849. Size to the optical zone: reed under 150 sq ft, Sukoon ₹1,899 to 320.
The only warm register in the range, and it needs a door
SOSA Fresh Brew · Coorg coffee & Kerala vanilla ₹849 / 50ml
The composition for an optical room that has its own air. Coffee over vanilla gives the body a display area can carry and a waiting room cannot. It sits at 9.5 on SOSA's own internal scale at six reeds, the highest in the range, which is why it is the wrong bottle for a shared air path: what reads as considered in a closed shop reads as a café in a corridor. Six fibre reeds rather than rattan, because rattan's pores clog in Indian humidity; alcohol-free, phthalate-free and low-VOC on a heat-stable coconut-derived carrier. 50ml runs 6–8 weeks, 130ml ₹1,349 runs 14–18 weeks.
Part one — why optical is different, and what that buys you
Every other zone in this cluster is judged by how little it announces itself. The eyewear section is the exception, and the reason also sets the limit. Optical is retail, and retail is allowed a register that a waiting room is not — but the permission is issued by the floor plan, not by the category.
1
FACTOR ONE · WHAT MAKES OPTICAL A GENUINELY DIFFERENT ROOM
People stand, handle objects and make a choice — that is a shop, and it behaves like one
In a waiting area people sit still for a long stretch with nothing to do, and everything about the dose follows from that. In an optical section they are upright, moving between display walls, turning to a mirror. The exposure is short, active and voluntary, and short active exposure tolerates a fuller composition than a long passive one does. A second difference matters more than it sounds: an optical section has more hard reflective surface per square foot than anywhere else in the building, and hard surfaces absorb almost nothing. A scent there travels further and lingers less — less material to register, and less warning when it drifts.
The rule: the retail register is earned by what people do in the room, and capped by where the room's air goes.
2
FACTOR TWO · THE FLOOR-PLAN TEST, WHICH DECIDES EVERYTHING
Walk from the frames to the consultation corridor and count the boundaries
Sukoon 500ml₹1,899 · optical zoneStand in the middle of your frame display and walk the shortest route to the first consultation cabin. Count the things that would stop air: a door that is normally closed, a lobby with two doors, a change of level, a full-height partition with the AC supply on one side and the return on the other. An archway is not a boundary. A half-height display run is not a boundary. A change of flooring is not a boundary — it is a change of flooring, and air walks over it without noticing. If you counted zero, your optical section and your clinical corridor are one air path, and the warmer-register conversation is closed for your building. If you counted one real boundary, you have a retail room and the rest of this page is written for you.
Test it in a minute: if you cannot name the thing that stops the air, there is nothing stopping the air.

FACTOR THREE · WHAT "WARMER" ACTUALLY MEANS HERE
A half-step, in one direction, with a named ceiling
Warmth in fragrance is not volume. A practice that asks for a warmer optical scent usually gets sold a louder one, which is a different thing and a worse one. What I mean by warmer is a composition with more body at the base and less brightness at the top — and what I do not mean is a higher setting. In the SOSA reed range exactly one composition does this: Fresh Brew, Coorg coffee over Kerala vanilla. Garden Bloom at ₹799 is rose and jasmine — floral rather than warm, and floral weight tips a medical building into feeling like a spa. Evening Calm at ₹799 is the softest thing we make and reads as a bedroom. And there is a gap to name: no oud, no musk, no amber, no aquatic.
Part two — six optical layouts, and what each permits
Here are the six arrangements I see most often in Indian eye clinics. Find yours in the first column; the last column is the only recommendation you need from this table.
The floor-plan audit · what your layout permits
Six optical layouts, judged on where the air goes next
| How your optical section sits | Air path to the clinical corridor | Warmer register? | What I would actually run |
|---|---|---|---|
| Separate optical room, door normally closed, own entrance ★ | Broken — a door is a boundary when it is shut | Yes, a half-step | Fresh Brew, or a Sukoon on low inside that room |
| Optical room off reception, door usually propped open | Open in practice, whatever the drawing says | Only if the door is genuinely kept shut | Decide the door first. Until then, the reception scent |
| Optical alcove off waiting, corridor on the far side | Continuous — optical air crosses waiting to reach the corridor | No | One composition, one reed more in the alcove bottle |
| Frame display along one wall of the waiting room | The same air as the seating; there is no second zone | No — nothing to make warmer | Nothing additional. One source for the whole arrival zone |
| Optical at the front, clinic behind, one long lobby between | Long and indirect, but continuous unless a door exists | Half-step, if the source sits at the street end | Source between the frames and the street door, never mid-lobby |
| Optical shares a ceiling void and one AC loop with the cabins | Shared mechanically, whatever the walls do | No, and no HVAC mounting either | Freestanding and low on the retail side — or nothing |
| The honest caveat: this table describes how air is likely to move between rooms, not how anybody experiences a fragrance. No claim is made about comfort, anxiety, browsing, purchases, footfall or revenue, and no product is described as safe or unsuitable for any patient group. Whether fragrance belongs anywhere in your building is a judgement for you and your clinicians, and SOSA does not advise into it. | |||

The SOSA principle
The eyewear section earns a warmer register because of what people do in it, and loses that permission because of where its air goes. The category grants it; the floor plan takes it away, and the floor plan wins.
Which is why this page is mostly about walls and doors.
Part three — when the eyewear section should get nothing extra
There are several optical sections I would leave exactly as they are, and the first is the commonest arrangement in the country. If the frames are a wall of the waiting room, you do not have an optical zone — you have a piece of furniture in an arrival zone. Adding a second source there is not zoning; it is doubling the dose in a room already carrying one, and the extra material will find the corridor before it finds the display.
The second is an optical room that shares a ceiling void or an air-conditioning loop with the consultation cabins, which is commoner than the drawings suggest. Walls that stop at a false ceiling stop nothing that matters here. If the supply and return for your optical room and your cabins sit on the same loop, the two rooms are one air path regardless of the partition between them, and the only safe specification is a low freestanding source on the retail side or nothing at all. In a clinical building I would not mount a diffuser into shared ducting under any circumstances — it delivers fragrance to every room the system serves, including the ones that must stay clear.
The third case is supply. SOSA does not currently sell a separate cold-air refill oil for the Vaayu. The 400ml supplied in the box lasts roughly ninety days or more at a mid setting and is the whole supply available at the time of writing. For a home that is an inconvenience; for an optical business that has decided its display area smells a particular way, it is a business problem, and worse across several branches. The water-based Hotel Collection is made for ultrasonic machines and must never be used in a Vaayu; those scents are inspired by the atmosphere of well-known hotels, and SOSA is an independent Indian brand unaffiliated with any hotel group. Confirm refill availability through the contact page before committing an optical section to a Vaayu.
The eyewear section is allowed to smell like a shop. Whether yours is allowed is decided by a door, not by a decision.

Part four — what to specify for the optical zone
Measure the optical section alone — not the clinic, and not reception plus optical unless they genuinely share one open volume. The last column is the one that keeps you honest.
Sized to the optical zone
Six optical zones, with a starting setting and a boundary condition
| Your optical zone | Specify | Start at | The condition attached |
|---|---|---|---|
| Separate optical room, 120–150 sq ft, door kept shut ★ | Fresh Brew 130ml ₹1,349 on a tray, far end from the clinic wall | Four reeds, not six, for the first fortnight | The door. If it starts being propped open, the bottle changes |
| Separate optical room, 150–320 sq ft | Sukoon ₹1,899 with a 15ml Hotel Collection scent | Lowest intensity, 4H timer set to trading hours | Ultrasonic, so it adds humidity — keep it off frame stock and paper |
| Optical alcove sharing air with waiting, under 150 sq ft | The reception composition, a second small bottle in the alcove | One reed more than the reception bottle — the whole half-step | No second fragrance. Two scents in one air path make one muddled scent |
| Frames along a wall of the waiting room | Nothing extra. The arrival-zone source already does this room | ₹0 today | Adding here doses the corridor, not the display |
| Optical floor plus its own reception, 320–800 sq ft connected | Vaayu ₹11,999, freestanding, key-lock on, run window at trading hours | Lowest intensity. Under 38 dB, so nobody hears it | Never HVAC-mounted in a clinic — and confirm refill supply first |
| Optical sharing an AC loop or ceiling void with the cabins | Nothing, or one low freestanding source on the retail side | ₹0 until the air path is understood | A partition that stops at the false ceiling is not a boundary |
Honest notes for buyers: nothing here is medical, clinical or safety advice, and no SOSA product is described as safe or unsuitable for any patient group — that judgement belongs to the practice and its clinicians. A diffuser adds a scent to the air; it does not clean, purify, filter, sanitise or disinfect air, and does not remove disinfectant, damp or occupancy smells. No claim is made about comfort, anxiety, waiting time, browsing, purchases, footfall, reviews or revenue. Some people are sensitive to airborne fragrance, which is why the clinical pathway stays fragrance-free and a fragrance-free seat should always exist. Coverage figures are manufacturer specifications and vary with ceiling height, air exchange and occupancy. Megh at ₹3,499 covers about 215 sq ft — less than a Sukoon — so it is a runtime machine, never a coverage upgrade. Safar at ₹3,999 has no published coverage figure. Reed strength figures are positions on SOSA's own internal scale at six reeds; replacement reeds are not sold separately, and there is no oud, musk-forward or amber composition in the range. SOSA sells no room spray, and no bulk pricing, corporate account, maintenance contract, installation service or warranty term is published — ask through the contact page first.
The open-plan answer, and the one most clinics need
SOSA Mountain Breeze · Himalayan pine, sage & Indian cedar ₹849 / 50ml
When the optical section and the waiting area share one volume — which is most of the time — you are not choosing an optical scent at all. You are choosing one composition for the whole arrival zone, and this is the one I would use: pine and sage over Indian cedar, dry and green, no sweetness, no floral weight. The half-step you are allowed is a second small bottle at the display end carrying one reed more than the reception bottle — a difference in density, not in identity, and the only kind an open plan can hold. 50ml runs 6–8 weeks at six reeds, 130ml ₹1,349 runs 14–18 weeks. Keep both on trays, out of reach, away from the corridor mouth.

A note from Sonal
An optometrist sent me photographs of a new optical fit-out — walnut cabinetry, warm lighting, brass trim — and asked which of our compositions would suit it. I asked for the floor plan instead, and the answer was in it: the display ran along the wall opposite the consultation corridor, with nothing between them but four metres of open floor. The room he had built was retail. The air it sat in was not.
We did not put Fresh Brew in that clinic. We put the dry cedar composition his reception was already running, one reed higher at the display end, and left it. He was not thrilled — he had spent real money on a room that looked like a shop and I was telling him it could not smell like one.
Six months later he opened a second location where optical sits behind its own door with its own entrance from the street. That room runs Fresh Brew and it is right there. The composition never changed; the architecture did. That is why I ask for a drawing before answering a question about a scent. Made in Pune in small batches, and a part of every order funds a girl's classroom through Nanhi Kali.
Frequently asked questions
Can the eyewear section really smell warmer than the rest of the clinic?
Only if it has its own air. A separate optical room with a door that stays closed can carry a half-step warmer register — in the SOSA reed range that is Fresh Brew at ₹849. If the frames are a wall of the waiting room, there is no second zone to make warmer, and the answer is one composition at one level for the whole arrival area.
Is there a leather, oud or amber option for a premium optical display?
No, and I would rather name the gap than stretch something into it. The SOSA reed range has no oud, no musk-forward composition, no amber and no aquatic. The five reed compositions are Fresh Brew, Mountain Breeze, Morning Freshness, Garden Bloom and Evening Calm, from ₹749 to ₹1,349, and the warmest is Fresh Brew. SOSA also publishes no bespoke, private-label or custom-fragrance service.
How big is an optical section, for sizing purposes?
Measure the retail floor alone. Most optical bays inside an Indian eye clinic come out between 120 and 320 sq ft, which puts a reed diffuser under about 150 sq ft and a Sukoon at ₹1,899 from roughly 150 to 320. A Vaayu at ₹11,999 is rated to about 2,000–3,000 sq ft and earns its price only past 320 sq ft of connected retail volume. Do not size to the clinic — most of it is not being scented.
Where should the source sit inside an optical section?
At the far end of the retail run from the clinical corridor, at waist to chest height, on a tray, out of reach. Not on the dispensing table, not beside the fitting mirror, not on the counter where an optometrist works all day — staff exposure is the constraint that matters most, and they are the people to ask about the level. Never in the return-air path of the air-conditioning, and never mounted into shared ducting.
Our optical room has a door but we keep it open. Does that count?
Not while it is open. A door is a boundary when it is shut and a doorway when it is not. If it genuinely stays closed through the trading day, run the warmer bottle. If it is propped open every morning because the room feels cut off, treat the optical section as part of the arrival zone and use the reception composition. Decide the door first; the fragrance decision follows it.
Optical retail · inside an eye clinic
A warmer register in the eyewear section is a floor-plan decision before it is a fragrance decision
Separate optical room with a door that stays shut: Fresh Brew from ₹849 at four reeds, or a Sukoon at ₹1,899 on its lowest setting for 150–320 sq ft. Sharing air with waiting: the reception composition at one reed more, nothing else. A Vaayu at ₹11,999 only past roughly 320 sq ft of connected retail volume — freestanding, key-locked, never mounted into shared HVAC in a clinic. A diffuser adds a scent to the air; it does not clean or purify air, remove any existing smell, or have any clinical effect.

Bluetooth app plus onboard controls, 1h / 4h / 8h / 24h run windows, day selection, adjustable intensity, auto-stop and key-lock. Under 38 dB. DC 12V / 1A, 5W. Freestanding or wall / HVAC mount. CE, RoHS and SGS certified. SOSA does not currently sell a separate Vaayu cold-air refill oil; the 400ml supplied in the box is the fragrance available at the time of writing, so a practice planning continuous or multi-site use should confirm current refill availability with SOSA before committing. The water-based Hotel Collection is made for ultrasonic machines and must not be used in a Vaayu. Other machines: Boond 300ml ₹899 (~150 sq ft, ultrasonic) · Sukoon 500ml ₹1,899 (270–320 sq ft, 16–18 hours on low, remote and steady/2H/4H timers, three 15ml fragrances included, ultrasonic) · Megh 6L ₹3,499 (~215 sq ft — a runtime and humidity machine that covers less than a Sukoon, never a coverage upgrade) · Safar ₹3,999 (waterless cold diffusion, cordless, 20ml, about 6.9cm, three speeds, 1/2/3-hour auto-off — sold as a car and travel diffuser, personal-scale only; SOSA publishes no coverage figure for it) · Aangan ₹25,999 (HVAC nebulising, ~8,000–10,000 sq ft) · Meenar ₹38,500 (commercial HVAC, 12,000–18,000 sq ft). Water-based Hotel Collection for ultrasonic machines: 15ml ₹299 · 100ml ₹999 · 300ml ₹1,799 · pack of seven ₹1,799; scents are inspired by the atmosphere of well-known hotels — SOSA is an independent Indian brand and is not affiliated with, endorsed by or supplying any hotel group. Reed diffusers ₹749–₹1,349 (50ml 6–8 weeks, 130ml 14–18 weeks, six fibre reeds, no 100ml size; replacement reeds are not sold separately). Reed oil cannot be used in an ultrasonic machine and Hotel Collection oil cannot be used in reeds. SOSA sells no room spray or home spray — every SOSA spray is a car perfume. Nothing in this guide is medical, clinical or safety advice. A fragrance diffuser adds a scent to the air. It does not clean, purify, filter, sanitise or disinfect air, does not remove or neutralise disinfectant, damp or occupancy smells, and has no effect on comfort, anxiety, waiting time, recovery or any clinical outcome. Some people are sensitive to airborne fragrance, which is why this guide recommends that examination rooms, diagnostic areas, consultation cabins, procedure suites and post-operative areas remain fragrance-free, that a fragrance-free seating option always exist, and that a diffuser is never mounted into shared HVAC in a clinical building. Decisions about clinical policy, ventilation standards, infection control and patient suitability rest entirely with the practice and its clinicians. A persistent stale, damp or disinfectant smell is a ventilation, moisture or cleaning problem — SOSA sells no dehumidifier and no air purifier, and fragrance should never be used to cover one. Coverage, runtime and longevity figures are manufacturer specifications and typical ranges, not guarantees, and vary with room volume, ceiling height, air exchange, occupancy and season. SOSA publishes no commercial or bulk pricing, no corporate account, no annual maintenance contract, no installation service, no stated warranty term and no multi-location programme; warranty length, spare parts, servicing and app platform availability are unconfirmed, and larger or multi-site enquiries should go through the contact page before any commitment.
