I agree and I want to also say that I haven't mentioned that kind of suggestions to op for buying second-hand hardware wallet.
I did not imply you said this. I wanted to warn OP that there are two main choices: use open source, non custodial wallet, free; purchase hardware wallet. But with the second option, ONLY purchase official and completely new wallet to use. NEVER purchase a second-hand hardware wallet, with risks mentioned.
Those who buy second hand hardware must be fool public. I will suggest second hand hardware wallet only when someone wants to buy it as a show piece at home. And thinking that a person will be completely safe by buying a hardware wallet is not correct, the device with which the hardware is integrated must also be safe. Moreover, the links that you have shared are effective to keep the fund secure.
They at least try to secure their fund and knew that hardware wallets can help them to do this but they did not know all things.
Open source wallets must be another important thing for them to consider.
Risk of second hand hardware wallets must be known.
If you spend money a wrong way, it won't help you.
