I have been really sad to give bad review but this product is not that much good.
Because I am having samsung split 1.5 ton ac that doesnt work properly and when we compare this to carrier ac and voltas ac than our disappointment increases they should do work on instant cooling if I starter my ac than my room should be chilled in next 20 min but chilling is not in the dictonary of samsung and if I turn off ac than my room should be cool till appropriate time but after 10 min I start feel warm.
