A lot of people trust Amazon and expect them (or their sellers) to sell a fuse that works. A lot of us make a dozen decisions about what to buy every day, and sometimes you don’t have time to do a bunch of research. This isn’t a problem that should only be pushed onto the individual buyer. There should be some required testing on safety critical products. It wouldn’t even cost that much to have an electrical engineer spot checking a few of the products.
