They are pretty awesome. I used them with a nunchuck for a multisig test and it worked really well. Nunchuck allows for signing through QR codes so you can just have tap signers securely in different states and still have no problem signing within a short amount of time. Much more user friendly than hard wallets for tech challenged family members.
