I have used SoloKeys since v1. Currently own two v2 SoloKeys, and they "just work" for anything involving FIDO2. I specifically use them for storing SSH private keys and WebAuthn credentials. The key can be used on any device with a USB-C port (there is also a variant supporting NFC, but I don't have that variant)
Despite being a bit careless with my keys (e.g. leaving them in a pocket and washing said clothing), they still work just fine. I highly recommend SoloKeys to anyone who wants to support open source hardware and firmware.
