I only see this as a means to advertise your wallet (entheca), I check online about the wallet review, I noticed almost nothing reviewed about the wallet, this means people are not using it, and it will be very difficult to ask people question about what they know nothing about, it is better to go for highly known and reputed hardware wallet. You also do not even describe anything about the wallet, although I will prefer to go for reputed ones and yours (entheca) has no review yet.
Know that hardware wallet is very safe to use, it is one of the safest wallet, but that does not mean it is 100% safe for people that do not concern about online security and privacy, because there are still malware that can change the recipient address to hackers address when about to send Bitcoin or other crypto on any wallet, but it is we that needs to give our wallet 100% safety.
Hardware crypto wallets can guarantee you not only complete anonymity
It is better to use pseudonymity, and only for people that are conscious about it. There are online wallets that can provide pseudonymity, and there are online wallets like Wasabi that CoinJoin for privacy reasons. Using hardware wallet for pseudonymity is possible, but also possible on online wallets. I think you can just only comment about how safe hardware wallets are and how they store private key offline rather than pseudonymity.
The most reliable and proven cold crypto wallet is Entheca
How is it reliable when people are not using it, please provide good reason why it is even reliable at all. To me, as I did not find much about it online, I do not think this wallet is reliable.
