Review on 🔑 FEITIAN MultiPass K16 Security Key: FIDO U2F Two Factor Authenticator with Multiple Interfaces - USB-A, NFC, Bluetooth by Will Rahman

Backlight works but that's it. Doesn't want to connect to my phone via Bluetooth/BLE, NFC works with it and all attempts to use it fail with a USB error. The documentation is pretty poor and there is no support or real information on the manufacturer's website. From a purely aesthetic point of view, it's way too big (you can hide an anniversary underneath) and thick to be friendly with a key ring. I also very much doubt that it will survive a drop in a puddle, with an open USB port, a visible gap between the button and the body, and a hole in the back for no reason. Return and buy something else.
