Just ran across this video where a guy tests "no name" automotive blade fuses and name brand Eaton/Bussmann and Littelfuse fuses, and the results are pretty much what you would expect.
Spoiler alert - the no-name 5 amp fuse didn't blow even with 20 amps for over 3 minutes. The Eaton and Littlefuse did.
