Thank you for taking the time to have a look and give some feedback!
- The very first thing that I noticed was the lack of a light/dark mode button.
I've implemented a dark mode through system settings so when you switch your settings, it should switch as well.
- If I were you, I'd remove the User Experience field or rather, the ability to rate these services, since anyone can easily alter them [unless you can come up with a bullet-proof way to tackle it].
How could anyone alter it, you think? I've tried to make sure one vote per IP address. The community aspect is something I think could be of value. 
There are plenty of missing HWs that either support only Bitcoin [e.g., Foundation Devices] or offer Bitcoin-only firmware [e.g., Trezor].
- You can find more of them on "this" website.
You're right, it's still missing services. The project is still in it's infancy so I had to make a selection but I will add more of them when users find the website useful. Thanks for the suggestions, it helps me a lot!
