"I stopped rebuying little bottles. One 500ml Garden Bloom refill has kept my living room diffuser going for over a year. Same rose-and-jasmine scent, a fraction of the cost."

When are wax melts better? When you like changing scent often and do not mind a warmer - melts are quick to swap. But they need topping up and a heat source.
Do reed diffusers need electricity? No - reeds wick passively with no power or heat, unlike an electric wax warmer.

Straight answer
A warmer and topping-up vs passive and lasting
Wax melts and a reed diffuser refill both avoid an open flame (if you use an electric warmer), but the effort is very different. Wax melts need a warmer and the fragrance burns off in a few hours, so you refresh the melt regularly - great if you love changing scent often, but a hands-on ritual that needs heat or power. A reed diffuser refill is passive: the reeds wick the oil with no heat and no power, scenting a room for months on one fill, with nothing to swap. For an effortless base scent that just runs, the reed refill wins; keep melts if you enjoy rotating scents by the day. From ₹2,399.
One line: wax melts need a warmer and frequent refreshing; a reed refill runs passively for months with no heat - the effortless base.
