In my book that's not too far off from an "official" ethereum wallet.
Mmh thanks, well security is more relevant to me, but I nevertheless went to their website.
Apparently it's a browser plugin. That's a big security no-no from my side, too much attack surface - sorry.
Hardware wallets are extremely insecure IMHO:
The people who sell them - and many people in their supply-chain! - are handed the very dangerous combination of:
A) Being able to hard-code software into the silicon whose source code you will be completely unable to inspect unless you own an electron microscope and a very large amount of knowledge on hardware reverse engineering. What if the hardware forces the PRNG to be predictable so they can remotely know my crypto's private keys without any internet connectivity whatsoever?
B) Knowing 100% for sure that the device they sell will be used to store money. They don't need to first find victims, they know ALL of their customers can be. It's like writing "MONEY INSIDE" on your house IMHO. Better use a general purpose PC whose vendor doesn't know what it'll be used for.
