My main grouse with all double-door/frost free fridges of today of whatever manufacturer is that these are not tailored for Indian conditions. These models were designed in the west for the west (by west I mean the meat eating world). They have been blindly imported and sold to Indians who are mainly vegetarians.
A typical DD fridge has nearly 40% capacity allocated to the freezer. And when it goes to the high end / high capacity models the ratio is even more skewed. For DD SBS fridge this is nealy 45%. Most of the time this space is wasted for Indians. Other than ice trays and sometimes a block of icecream there is nothing occupying this space.
The fridges of yesteryears including the double door types were designed with the Indian requirements with the freezer taking at most 20% of the capacity. Recently at Croma, I observed a family eagerly looking at a SBS DD fridge. I couldn't help asking the lady, "Madam, tell me what are you going to fill the freezer section with? This may be a 720 litre fridge but in reality you are buying a 400 litre model." Whether my comments made any impact or not, I do not know.
While the theory may not apply to all, one should consider the optimum, nay maximum usage of available space in a fridge.
