Pretty basic
However, it does what it needs to do. I set a pin and set it up via Apple iCloud (along with a Yubico USB-C NFC backup FIDO key). Center button is capacitive touch for user initiation. Touch it when asked. Make sure you have a compatible device as well. Reset function has a security feature where key card can only be reset within 8s of plugging in. Seems obvious, but remove key from accounts before doing that.
