Pros: Portable, light weight, movable on wheels, looks stylish, variuos fan speeds, easy operation.
Cons: Big list here. Motor failed to work after 4months need to be replaced. Not a standard motor. Same Motor not available in the market. Runs 2 to 3hrs after that water should pour in to it. Bad service. Not enough cool air. Sufficient for 2 persons that too within 4 to 5 feet distance. Not sufficient in even small room. Not sufficient for very hot summer.
Verdict: For air coolers go for assembled blowers which are far cheaper and better than these branded coolers which are nearer the price of air conditioners.
