Limiting oneself to a subset of information is not how one makes an informed decision.
I didn't say anything about reading every possible review. But you do need a good, rounded sample.
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.
Sellers are well aware how much of a boost a photo or video from a verified purchase can give.
