Thanks for the feedback. I'm working on a model with USB-C now. 😀
One advantage over bitwarden is that the backup file can be stored offline and the device provides physical control of the passwords. Nothing has to be on an always online server.
I might add a comparison between bitwarden and Signet. I do like BitWarden and look forward to setting up a self-hosted version for an organization that I'm part of. That'll give me a deeper understanding of their internals so I can better compare and contrast.
