Onekey classic is an open source hardware wallet, but i don't think it is all that recommended by the community, when i read about this hardware wallet, i learnt that they cloned Trezor's code, so if i were you, i will do my research very well about this wallet before i use it or it's better if you simply go for recommended hardware wallets like Passport. Unstoppable wallet is an open source software wallet and i would recommend it if you need a wallet to store your shitcoins, that's because it is a multi-coin wallet.
One of the hardware wallet that I can not recommend is Onekey.
A vulnerability was found with the wallet this year:

Dkbit98 posted that the developers add bugs connected with the hardware's secure element.
OneKey is biggest hardware wallet manufacturer from China and they are very popular there, but they mostly cloned code from Trezor.
From my own experience after talking with them about working together on one project, I can say they are semi-amateurs and liars.
I can't seak much about quality of Onekey wallets, but I know they had serious bug connected with secure element, and I wouldn't really use any Onekey device as a main hardware wallet.
There are good options available.
For bitcoin-only wallet, Passport is still the best, but let us see when upcoming Coldcard and Keystone hardware wallets would be released and see the features they come with.
