Excellent. I can't get enough. Great support, lots of tutorials, plus features with Yubico Authenticator. At this point, it's almost impossible for someone to hack your account because they would need to know your name, password, have your key and PIN (if you protect it with a PIN, which I recommend. )
It's so tiny, I didn't expect it.
It flashes when it has a call to touch.
100 passkeys (previously only about 20)
64 OTP codes (previously only 32)
Two slots for quick functions (triggered by a long or short touch)
Challenge-response function, suitable for unlocking the KeePass password database, for example.
Support for SSH two-factor authentication (there is a nice tutorial on the Yubico website on how to use Yubikey to password-protect your server account and have it accessible from any device - just generate a code from the key using ssh-keygen -K; but the residency code must be set, otherwise a different kind of key is generated, which has a secret key in the folder. ssh).
Yubico Authenticator - great app for managing (basically better than Yubico Manager) and OTP. I don't think there's any better protection for your codes.
European technology at the cutting edge of the world.
It's really small, so it gets a bit lost in Orbitkey, maybe it's better to have it on some string.
It doesn't have NFC, but since it's USB-C, it will work in a cell phone.
You can't export stored OTPs (which is not a bug, but actually a security feature), so it's a good idea to store your secret keys somewhere secure, ideally in encrypted form on a disk somewhere, or print it out for me.
If you have multiple keys (which is highly recommended), it's a bit of a hassle to upload the OTP code to them. (E. g. Ente Auth allows you to display a QR code, so you display it on the screen and click in Authenticator, where you can manage multiple keys at once, up to 4, just click to add the code and read the QR one by one. it's not fast, but it's definitely a little annoying; however, the goal is not to have all OTPs on Yubikey, but only the most important ones).
Unlike GoTrust, Idem Key does not have open-source software.
The PIN on OTP passwords has no protection (theoretically it should be discoverable by brute-force attack; does not apply to the FIDO2 key).

The product itself is good, but some browsers and sites cannot authenticate you. Probably works if you just stick to Chrome (but you shouldn't)

An interesting and workable second security element (U2F) solution with many possible applications
Configurability via manufacturer's software to different protocols
Possibility to place on keys if needed
USB C compatible with mobile devices
In my opinion, the key ring is made of too soft plastic, after one fitting and removal on the key ring there are deep grooves on it
