I've used Forefront cases for many years now, including on my current Libra 2.
I think I may have had one many years ago where the magnets didn't close strongly enough, so they changed it. Nothing's perfect, problems will occur from time to time, and it's how they're dealt with that matters. They didn't quibble at the exchange and the replacement worked.
All the others have worked fine.
