Ok. Started to wounder about my backup device (model one) that I probably don't need it since it's so easy to restore it on electrum. I haven't decided yet but what is your take on a backup device?
Trezor T is my "daily driver" because of its enormous screen and passphrase entry. I use Trezor One as a backup since I got it for free for helping out with Trezor web interface translation. It's small so it is fairly easy to hide. Anyway, if something happened to my Trezor T, I would buy a new one. I have some coins on my phone (Samourai wallet) just in case I needed some money.
I also had Ledger Nano S and Nano X. I guess I'll stick to Trezor and Electrum if I ever need to recover my wallet. You should be fine with Electrum if your device breaks or gets lost, but don't import your seed there unless it happens.
