I haven't heard any complaints about the metallic version, but honestly I haven't seen much talk about them at all. It's fitting that the version that looks so good has such fundamental flaws...that's life, eh?
Ok, I'll look into the plastic version.
Have you hand any experience with the metal private key holder?
Thanks.
They are easily identified as crypto-related and in case you lose it or someone finds it, put all your bits are gone. Yeah it's stainless, waterproof etc, but so is a piece of paper.
Paper dissolves in water and is stained by almost anything. If paper were a safe option Trezor wouldn't exist.
If you laminate it and store it somewhere safe (say I buried it in my garden inside a safe, for example) it basically couldn't get any safer than that since it's immune to cyber attacks. You could even have a second paper wallet stored in a different place and then you'd be safe against a 5-dollar-wrench attack (just tell them where that one was containing only a small amount of Bitcoin).
TREZORs are very secure but their main purpose isn't to be safer than a paper wallet, it's to be better for everyday transactions than a paper wallet while still being secure.
