And the ratings, if you read them carefully, help keep you from buying crap products. I’ve bought so many things that were junk, or turned out not to be a good design, that I had a saying for a while that 97% of everything you buy is crap.
I read the ratings and they are helpful. I never buy anything that is not rated 4 stars or up. Most of what I’ve purchased has been satisfactory.
Sometimes the comments/ratings are very funny. :)
