This really a decent product at this range.I am using this product for three and a half month in 17x20 foot room.it takes generelly takes 10 min to make it enough cool .the ac does not sounds so much .but I am having some problem to operate the timer option. but it is really my own fault.I am also use this in winter to make my room temperature average .it is also user friendly to me .i think this is very satisfying for most of the users.i bought it from a local dealer BY EMI from bajaj finanserve with 0% interest.it caust me about 40 thousands. it is really a value for money at this range.
