A compact, essential security device
This works as it should; just plug it into a USB port and tap the button or tap it against an NFC-enabled device. I love the idea of requiring a physical key in addition to my login credentials. It's a superior option to SMS authentication and a personal preference over authenticator apps. I just wish more services supported this technology.
As for the build, It's about the size of two US quarters laid side-by-side, so it doesn't add extra bulk to your keys should you decide to attach it to a keyring. It seems durable, made from a hard plastic that doesn't easily snap, and should withstand typical everyday abuse.
Overall, I'm wholly satisfied with this device.
