The only mark(s) on their brand are:

1. AFAIK, they have suffered a data leak similar to Ledger.

2. They insist on supporting other cryptos.

Both are just things for a customer to consider before deciding to make a purchase.

The only other thing is that after watching this video, it felt like they made a premium product with a heart disease. Beyond being hard to crack, it is also hard to break or damage, but any attempt to tamper and it is broken anyway.

Feels pointless to make an expendable product premium.
