When buying a product I look for the reviews about it breaking. Once I know all the common ways the product might break I have a bit of an idea how long it will last. I can then also look up how much the replacement parts for the most likely to break parts cost as well as how hard they are to replace.
In my experience a lot of products have a single design flaw that causes almost all of the breakages excluding drops/water damage. I had a set of skullcandy headphones that the little arm thing on the ear part would snap just from the force of putting them on and taking them off too many times. Got a replacement and it happened again. Checked reddit and saw everyone has this same problem. Ended up getting the store to exchange them for a different pair.
