Hey guys I am here to share my true opinion on this usha 55 liter honeywell air cooler. my father bought this cooler last 2 years ago. after using some months I found that the cooler is not working properly. firstly it get noisy. it produce a lot of sound which create disturbance, according to the expectation the cooling is not good.as compare to this cooler the other coolers with latest feature are doing good job. and it is also high in price. hope my review helps you.!
