### ⭐⭐⭐⭐⭐ exactly what it says it is

exactly as ordered

### ⭐⭐⭐⭐⭐ Easy to Setup and Just Works Even With a USB-C to USB-A Adaptor
*by W***E on November 10, 2025*

Very easy to setup in Windows and add as a login in key for many accounts already.

### ⭐⭐⭐⭐ Excellent value!
*by T***L on February 22, 2026*

Small form factor security key. Verified by me to work with Google accounts, Login dot Gov and Bitwarden. Excellent value for the money as compared to others that charge twice as much. Two things that I didn't like. The first is that you have to use the Thetis key manager application on Windows, Mac or a Linux computer to set the PIN on the key. Thetis does have an Android app however, that app doesn't have the ability to set a PIN on the key. This could be a limitation of the Android OS but I don't know for sure. The second issue I have is that the key should have come with a cap to protect the USB C connector. The key does work with a USB C to USB A adapter. Bottom line is that this is a good value but keep in mind that you will need a desktop or laptop to add a PIN to the key before you can start using it. If you laptop only has USB A connections then you will need an adapter. You might also want to get a lanyard for your new key.
