Probaby when it stops working. I have some old Ledger Nano S's (which I stopped using years ago) that the display screen has become very faint.

I have a Jade and a Coldcard still going strong. I'd like to test out some other HWW like the Coldcard Q, Bitbox, Frostsnap or Bitkey. I probably won't buy one of these until something breaks in what I have.
