When it works, speeds are good and browsing is not affected too much. It is not constant, it may be really quick and sometimes quite slow. Overall good.
Unfortunately, after some random time, it becomes impossible to do anything : browsing to new pages, refreshs. When it happens, gpu usage for firefox is high.
Only solution is to restart firefox which is destroying the usability.
It doesn't happen everyday and sometimes it happens multiple times per day...
I haven't tested the Windscribe windows app.

Edit : I finally switched to Opera for the cases when I need privacy. The windscribe extension can perfectly work some days but the others requires way too much restart of Firefox. I leave it with 3 stars because of the monthly 10Gb free limit.

Seems to slow down my accessibility to other sites. Takes longer than it does when it's turned off. So far, tho, other than that it seems to be fine.

The startup of the add-on is very slow. Also, after the startup of the browser page always reloads. Please fix it.

not so safe
work but not very good

i love it!

I like it but sometimes it's hard to get connected to the internet.

Windscribe offers awesome service. You're cool, guys!
However, I have a problem for a long time: some times a day Firefox stops to see any internet connection despite the fact that the connection is good. After restarting the browser everything is okay. I've noticed that this occurs only when I use Windscribe. Have anyone met such a problem?

utiliza muchos recursos del pc lo que hace que se cuelgue a cada momento perdiendo gigas de descarga ya que tengo que reiniciar la descarga y eso suma. Eso si, tengo 15 Gb al mes gratis por registrarme, confirmar el email y tuitear.

top speed
