I’ve moved my keys from Coinbase to a hardware wallet. I’ve stored my seed phrase in a safe deposit box at the bank. I’ll be stamping the seed phrase onto stainless steel washers and putting them onto a stainless steel bolt. And then storing that somewhere safe on my property.

Questions: (1) is there any reason to have a second hardware wallet? (2) does anyone use a read only wallet just to track your balance? If so, which one? Is there an app for that? Thanks.
