I can only speak about the ledger nano X which I bought about a year ago. This is basically a hardware wallet that also has an app on your phone which shows how much crypto you have stored on the device.

This device has worked fine for me, and it is relatively easy to use. As I said before though, the most important thing to remember is that if you loose the seed phrase that is created when you first set up your bitcoin wallet you will loose the crypto. This is essentially what keeps the BTC (and other crypto if you store anything else on the device) safe and offline. It is basically a paper wallet connected to a device so that it's easier to transfer to and from exchanges.

See this video below which is the one I used to initially set up my BTC wallet on my ledger and transfer BTC to it. Hope all this helps 🙂
