Our impressions

Pros

  • Has a great community and (d)app ecosystem

Cons

  • Outdated microUSB port
  • Needs constant USB connection

Our verdict

The product has a nice build quality and finish, a solid (d)app ecosystem, and a great community. The product launched in 2015 and it shows its age, compared to newer hardware wallet products. Most notably it has no secure element, a microUSB port, and limits itself to a single button for on-device input.

That being said, we would still prefer it over any software wallet, though.
