Nice. I'm glad to know that at least the device would be waterproof, even if it's not meant to be submerged in deeper depths. I think that with all the security features that this hardware wallet provides, it'll be the most secure wallet to date. None of the previous wallets such as Ledger Nano S, Trezor, KeepKey, etc have been able to provide unparalleled security for cryptocurrencies. I know that with additional security features, the price of the device would be higher, but I think that it's worth it considering that your cryptocurrency funds would remain impenetrable against external attacks.

What has attracted me the most about this wallet, is the ability to run a full node in it. That's something that's not possible with current hardware wallets and could further decentralize cryptocurrency networks as the level of accessibility becomes greater for an average person. All in all, this could be a very useful device once it's officially released from the company itself. It would be a matter of time before customers receive their pre-ordered devices and leave their reviews about the same.
