could already have lots of stuff so screwed,

annoying of course, Nintendo with such nonsense started, special screws to use, but that does not detract from the quality of gamebits here.
the metal is very hard and rustproof. at least I could not detect any wear. presumably it's not a very good price, especially for a bit more special three-point screws (eg in some Mega Drive cartridges) is missing. even very small cross-bits could be accompanied by quiet, especially the enclosed screwdriver is not that great either. after all magnetic.
Nevertheless, I give five stars, because I am about what was touted content clearly can not complain.
