There are only two or three big manufacturers left, and they each own many brands. They rotate which one is reliable to create more consumer confusion and trick you into buying major appliances more frequently.

The difference between a 3 year and 20 year fridge is usually only a few dollars (maybe 10), and has nothing to do with efficiency.

Case in point: The outer shell of new chest freezers are made of substantially thinner sheet metal and paint. This causes them to dent rapidly, and, in moist climates, rust through. It also reduces shipping and manufacturing costs, since it cuts the weight by a few pounds.
