Seedsigner is fantastic. Best UI in the market. The thing that sets it apart is that it doesn't abstract away hard concepts. Seedsigner is a tool for DIY financial sovereignty. In order to use it effectively you need to go on an educational journey from verifying software binaries to generating your own entropy to stamping out a metal backup. No hardware device can compensate for lack of knowledge or bad security posture. Most commercial devices try to make the 'least bad' tradeoff for mass market usability. They assume the consumer is ill informed and lazy. For the most part they are right. Seedsigner is for the folks who are ready to roll up their sleeves and be in control of their own security. I don't recommend it to everyone. But the people I do recommend it to are my favorite kind of bitcoiners. They aren't just buying a hardware device, they are digital survivalists learning skills necessary to thrive in the coming economy.
