So I could buy 2 set them up as clones and put one in a bank safety deposit box?
then if my in house breaks or is stolen I could go to my safety deposit box and access the wallet?
if true to both questions and you have a decent amount of coins I would consider buying it.
and if I was buying 2.
I may as well buy 3.
since 2 = 238 usd and 3 = 299 usd
You can't make clones, each device has a separate private key and even if you could 'clone' it, it would be pointless in purchasing more than one device.
Just make sure you never misplace your Trezor and your recovery card at the same time, then you would be truly screwed. If someone steals your Trezor they can't access your funds because you have a PIN setup, each time you enter the PIN incorrectly you get locked out longer and longer at each failed attempt. You would have plenty of time to get your recovery card from your safe deposit box and recover your funds before the thieve could ever access them.
