Just finished to build a npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl... Wow, the interface is marvelous! On such a tiny screen, it has been taken care of down to the smallest details and greatly paired with the joypad and buttons functions. Really great UX. The volatile memory + SeedQR concept is another clever UX win: fast to operate, secure, multi-seed. Furthermore, QR codes are a handy backup format, certainly less flashy than a 12-word list. Last but not least, it is a fascinating piece of hardware.
