I buy this ac almost 2 years ago. I buy this ac before this I used my companies ac such as lg, micromax etc. I am not satisfied with other companies ac. their service is not very good. they working well at starting 1 or 2 months and after that many problems are coming with other companies ac. then in last I buy samsung ac. it is working well and give me cool air in night and I have gone to sleep easily and rest. its sound is mute. and I cannot understand it will start or not. I like this product and I am the big fan of this product. I recommend to all if you want to buy ac then choose this and purchase from showroom easily. it is very good looking and it’s shape is very attractive. it’s service is very good and their customer care service is very good and they help customers more and more in any way.
