I just got a good price from eBay on a supposedly never-used Trezor hardware wallet. I have no specific reason to think this would be dangerous to use, but I'm being cautious and ask here first:
Are there any reasons why it would be unsafe to use a second-hand Trezor to store my BTC?
Is there any way the previous owner could retain access to it and get at my coins?
Any other risks to a used hardware wallet I should be aware of?
