I recently purchased a 310Ltr Whirlpool refrigerator.
Here is what study i had done.
Electrolux Kelvinator - Purchased by videocon - so no more a best brand.
Godrej - Its old player in india for other products and not for electronics like refrigerator or washing machine.
After my survey in Vijay Sales, Croma & few other reputed dealers in my area i figured out that LG, Samsung & Whirlpool are 3 good brands to go for.
I personally liked Samsung for their technology & smart space usage, more over they have 2 very attractive color available which i loved most and had decided to buy samsung only.
Unfortunately the space we had available was 33 inches wide and samsung 310 ltr required minimum 35 inch wide space so that door can open completely and then vegetable basket can come out.
Hence we thought of opting for LG & whirlpool, and figured out that whirlpool has good level of customization available and with 3 shelves it gives more storage space if one has medium or small sized vessels to keep in it. And the thing we liked was that only opening door slightly more than 90 degree to refrigerator, we were able to take out vegetable basket. Also we got several bowls and bottles and small air tight jars with it as complementary.
Sad thing is that it comes only in 1 color, but that is ok, quality is good.
My colleague recently purchased 200ltr whirlpool with battery backup of 3 hours built into the refrigerator itself
