I agree about the proprietary connector. Do they sell replacements if your connector breaks or is lost, or do you have to purchase another entire wallet? Bit of hassle since you can't even charge your device without it.

Is the only way to interact with this device via their mobile app, and is the cable only for charging and firmware upgrades? There is no way to plug this in to a laptop, say, and interact with your wallets via Electrum or similar?
