I know this HW because several members got a chance to test it for free, and they wrote their review. Furthermore, I think that at that time the biggest drawback was the price around $150 (now $99.99+shipping) which was a bit too expensive compared to the competition, and the fact that it is a card type HW, but crypto users do not prefer to carry these devices with them (mostly). In my opinion, another disadvantage is that this device only supports Android/iOS and does not work on desktop computers.
Otherwise, the device was actually pretty neat and worked OK. I didn't have any issues with it.
Having said that, I'd probably still go with either Ledger or Trezor if I were buying a new hardware wallet today. IMO, they still offer the best combination of price/feautres... If money wasn't an issue, I'd probably try a coldcard.
