It's pretty good. The little nub to select letters and pins and single button aren't too awful, and you can enter seed words right on the device. It's just a little fidgety at first getting used to it.

The screen is a little small so the software such as their Green wallet to connect to displays everything. But everything verifies on the device screen.

I only use Sparrow because of my amateur node set up. But Blockstream Green is a nice interface.

I'm no expert though. So. Im not shilling. Still want to get on the Coldcard train.
