It looks pretty cool. Their 2/3 multi-sig using the hardware key, your phone, and a 3rd encrypted key on the BitKey servers is really nice. Nunchuk Wallet does something very similar, but using Coldcard and Tapsigner, along with a 3rd encrypted key on their servers. And the price point is decent. Only $100 for the BitKey hardware do-hickey.

I currently use a Tapsigner as the key to my single-sig hot wallet, and I was thinking of getting a Coldcard to use with a new Taproot multi-sig wallet, but now I'm thinking of getting the BitKey. I'd like to hear some reviews from people who use it before I make my decision, but I know the BitKey is new, so it might be a month or two before we start hearing about people's experiences with it.
