I don't understand why anyone would take the risk of using a "USB hardware wallet", when it is not firesafe, and has the possibility of a software problem. I lean towards a "metal hardware wallet" like the ELLIPAL Mnemonic Metal OR Cobo Tablet .
Can anyone convince me that a USB wallet would be as safe?
Your metal hardware wallet still can't help you if you lose your recovery phrase, if you wrote it down wrong, or if the RNG the company uses is weak. Essentially, it doesn't matter. The brand you suggested is worse than the ones this discussion is about. You can purchase one made of titanium and it would still be weak.
On the other hand, if you take proper care of your seed, you can use a hardware wallet made of jelly and always recover everything from seed when your device melts.
