I have purchased kenstar slim line cooler and two season have gone but cooler giving cooling same as new cooler. It comes large tank as 40 letre & movable wheels. Kenstar is silent cooler & give more cooling flow compared to other brand. Kenstar slim line cooler price is very low which comes within all family budget. Kenstar providing 2 years warranty on cooling fan & 1 year warranty on water pump with special benefit like ON SITE WARRANTY. Kenstar comes with large cooling pad with air flow movable cutter. It is covered 30 meters area with cool air flow.
