Crypto hardware wallet comparison Trezor Safe 3 vs KeepKey
Our impressions
Trezor Safe 3
KeepKey
- Small form factor and very portable
- Excellent value at an affordable price point
- Phenomenally intuitive and efficient on-device recovery, PIN and seedphrase entry
- Has a great community and (d)app ecosystem
- Requires constant USB connection to operate
- Outdated microUSB port
- Needs constant USB connection
Finally the first line of Trezor products incorporating a secure element has arrived. In our opinion it easily takes the lead in the current Trezor product lineup – in terms of security and portability. Even with the launch of the newer Trezor Safe 5 it’s easily our price/performance winner.
Even though the device uses only two buttons for input, like the Model One did, and does not offer a touch-screen, like the Model T and Safe 5, its on-device recovery, PIN and seedphrase entry are phenomenal. Trezor really did something truly special with the way they handle user input despite the minimalist form factor. At less than half the price of the Trezor Safe 5 it is an easy recommendation.

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.
