If you stay in dry and hot area like Rajasthan, Delhi, AP, MP etc.
Where the air is hot and dry this is the cooler I’ll recommend.
I bought one a year ago for 6000 Rs. with stand.
It’s water storage is about 40 to 45 litres.
Just need to fill it once for the whole night, ofcourse it depends on air dryness.
The design is good, plastic body is tough. Pads are thick enough to allow air to be sucked in and cooled to circulate, it can cool area of about 300 to 350 sq. feet efficiently.
The internals of the coolers are great, the design is such that water will never fall on the pumpset so no question of damage.
But there is nightlamp like thing at the top but no actual night bulbs are there.
I feel if night lamps were actually fitted it would have been good. Also the power chord could have been a meter or two longer than it is. (or there could be variants)
