OneKey Classic is basically forked Trezor device that has similar price like T-Safe 5, and I would argue it's less secure than original Trezor devices.
Onekey had a big vulnerability in one of its hardware wallets in the past. I think that device got discontinued in the meantime. A security company managed to exploit Onekey very quickly and export the seed from the wallet. It was an encryption problem I believe. More precisely, a lack of encryption that allowed the seed to be intercepted. The issue was, of course, fixed in the meantime but it still leaves a bitter taste in the mouth.
