From my research, I'm convinced that a hardware wallet is very safe. I've been using a Trezor for about a year and a half and it has been great. I've heard yours is good, too, and probably they're about the same tool. Congratulations on a very wise purchase, @gringalicious !
That's awesome to hear about the Trezor. I am really glad to hear it's been good for you. And, I am glad to see that you agree it's a safe method of storage
