Major security risk that for this price not even a display is included. Even a cheap Ledger Nano S is better (with knowing the recent data breach news). I think it should be redesigned.
Given everything including the hardware will be open source, anyone can add a screen if they wish.
Everything is trade offs. Read our blog post on screens.
I think this product would be good for someone like my mom. Trying to walk her through the steps to receive bitcoin to her Ledger over the phone is usually an hour-long process.
