I purchased this refrigerator in last Summer. Actually, We had purchased Whirlpool product for the very first time in our family. We thought to give it a try. But, saying happily, It has been working flawlessly till date and I have not called any technicians yet.
Its a single door refrigerator. In terms of Cooling, I have not seen any problem even most of the time, we use it at the lowest point. It gives a feature of cooling backup of 12 hours with a power cooling vessel zone. Electricity consumption is 266 units/year, very affordable.
Overall, its a good product to have in home.
