I dont have any experience with a hard wallet yet so I am not qualified to even comment about them. There are several signs though to determine a wallet security.

  1. You alone got the access what's inside.
  2. You alone can recover your access.
  3. It is weather proof.
  4. You can access your wallet whatever happens.

and maybe you can think of something else. I think you'll get the idea :D Cheers!
