Simply a waste of money. It doesn’t provide cold air all the time. Hot air comes after an usage of 3 years. It is not efficient in summer.it is a very weighty product hard to move from one place to another. Cold air doesn’t cover even a half of room. If you seat infront of this cooler you will get the comfort or else not. Wheel at bottom of this product is not good it stucks while moving. Compressor is also very bad it sounds a lot when runs very warm air comes out from the backside of this product. It consumes a lot of power also no voltage consumption.
