Review: Blew me away for the price and features! - I was a little skeptical of buying this security key since YubiKeys are so widely recommended above all else but I’m been very impressed. I can confirm it is FIDO2 and can store TOTP’s within their apps. It does everything as advertised and I recommend this key as either your main key, or a fantastic cheap backup. I’ll go more in-depth below!! Hardware wise, it does feel a little cheap but I don’t feel like it would break within a month and for the price, it’s expected. I do like that it has the folding protector that covers the USB C port and makes it more modular. The button is also located on top so it’s very convenient to press and feels very nice. Software-wise, it does exactly what you would expect and works as advertised. It has NFC, FIDO2, WebAuth, and TOTP/HOTP support via their app which is on all PC and mobile platforms. Overall, I’ve been very impressed with this key and if you want the features of the 5 series YubiKeys without the high price (since you need a backup keep so that price adds up) and a built-in protector that makes it more portable, you can’t go wrong with this key and it’s especially recommended if you’re simply looking for a cheaper backup key.
Review: Solid product that is strong alternative to Yubico - Feels solid, and working great. Highly compatible with Samsung phones. I originally chose Yubikey but then had to return it since it wasn't compatible for android devices and the NFC and USB functionality was not working. This key isn't too large, fits nicely on my keychain to carry around with me. I honestly feel more protected now knowing that i have a easy to use this physical security key that safeguards the sources of digital vulnerability that I have taken for granted for way too long.

### ⭐⭐⭐⭐ Tricky to set up, but works wonderfully
*by J***N on January 31, 2025*

Device works as intended, but setting up is a little bit tricky. Software can be a little rough around the edges, and it takes a couple of extra clicks to choose a physical authenticator security key instead of a digital one, but it works perfectly once set up. It is small, easy to use, easy to carry around, and feels built well. This product is very solid, and works with windows devices well (I have not tested with other operating systems).
