Haven't fully tested it for leaks etc. But it looks good, and easy to install. Reliable so far.

Very Good and Very fast but it seems to disconnect randomly without any notification that it does so you dont know its not connected

I regularly notice that the Proton VPN icon is gray, meaning it is no longer connected, even though I was connected just a minute ago. Also sad that it is missing the Kill Switch, pretty important feature for a lot of users.

Nice idea, unfortunately it disconnects continuously from VPN.
UPDATE: the disconnections were fixed in the 0.1.7 release.

Would be nice to see what protocol is being used.

Works well and is simple to use.

It's a beta version but seems to work very well. Good job
