I bought a couple of Solo2 keys and I have to admit that I'm very disappointed. I clearly made a mistake because I bought the keys without checking the GitHub repository, when I did that I realized that the project was kind of dead. Today I have problems compiling the tool in rust and the binary version isn't working at all.
What I still find irresponsible is that in the official webpage they keep selling these keys when they clearly are not updating the firmware and they are not even updating the tool for more than a year.
I guess I might need to check Nitrokeys, the software and the project seems to be in better shape.
