Fingerprint + QR for MetaMask
Use it with MetaMask/Rabby for DeFi. QR signing is fast enough once you get the distance right. Fingerprint beats typing a PIN every time. Open-source angle mattered to me.

Michelle W.Verified PurchaseOakland, CAJan 16, 2026
Big screen, air-gapped
Camera on the device makes scanning less fiddly than my old Keystone. Triple SE marketing sounded like hype until I read the docs. Still no Bluetooth which is what I wanted.

Multi-sig friendly
Running a 2-of-3 with another signer. Setup took a Saturday afternoon and coffee. Screen is large enough that I actually read the tx details. Happy with the purchase.
