@dthompson I bought it more than a couple years ago, so I don't recall what I paid back then, but I thought it was >=60USD. The current Nitrokey Pro 2 price is ~54USD.

Absolutely worth it, though. I use it every day for SSH, signing email, commit signing, decrypting personal files, and some other things.

The U2F one is ~25USD, but it's not a smart card.
