Trezor is the best cold storage out there. This is saying there are no extra features? What that's just crazy! This has a password manager, a pass phrase secuirty that when you enter the incorrect password it will generate a completely different wallet. For exampl someone hold you hostage forcing u to give up ur password, give them any pass you want and it will show a completely different wallet. Come on this should be in the top 3 for wallets! It's easy to use, a noon might need showed once but that's it. So under rated here!
