BitBox01, Mycelium Entropy, Ledger Nano, ???, Ledger Blue.

Although I worked for Mycelium, I only had the Ledger Blue of these.

That 4th device ... I'm curious. Somewhere around 2014 I think somebody bought bitcoin from me using a device like this but it had a black and white e-ink display, a camera and a GSM chip that was supposedly paid for globally for many years.
