Usha 55 litres Air cooler is simply superb, we bought this in month of march last year, it is working efficiently and it has a unique feature compare to other air coolers. It does’nt use grass, instead it has some other material.
We no need to change the side grass every year, also the body is firm and suitable even to place it in outside of house.I bought it for 12999 rs.I suggest this even compare to AC guys.
