Bought to replace an ageing Bosch fridge that was about 25+ years old, I was very pleasantly surprised to find out how much the technology in fridges has advanced. I haven't had it long enough to notice a marked decrease in energy consumption, after all, how much can a fridge use in a year, but I am convinced it will make a big difference, with the closed and sliding shelves that must trap the cold air inside and the fact that you can easily find anything you are looking for in a short time so you don't have to keep the door open for long. I agree with the other reviews that nothing gets trapped at the back. Again, I haven't actually found a use for the tiny shelves in the door (chocolate bars??). I am delighted with my new fridge and would recommend it to anyone looking for a stand alone fridge. When my dishwasher finally hits the dust, I will be looking at a replacement from Bosch in the same range.
