Although it is widely believed that users' responsibility led to these thefts, but a single mistake could wipe me out.
That's true for any hardware wallet. So, think twice before you do something you might later regret. If in doubt, ask questions before, not before making a mistake.

Thank your suggestions.
I placed an order for OneKey, now own three different brands of hardware wallets: Trezor One, Bitbox02, and OneKey Classic. I will take care of the OneKey's open source nature and reputation, and will immediately disable it if anything bad happens.
