I never thought you would need to back up CNC machines! Now I know, that's why I bought them to be able to do that. I got one for each machine that had readers, so each machine had its own card. They worked great and I had no problems with them. They come in a nice little plastic case so they lie around protected and not used until the next machine backup.
