I love it!
The free plan is acceptable, and both the add-on and the application are not really intrusive (though you need to deactivate the auto-connect).
I am going to get to the paid plan to give them support because they really work: I tested several VPNs, and Windscribe is the one that worked better for Netflix on my Nvidia Shield.

One of the best and their FREE offer is so generous. Thanks for that!

VERY GOOD

Great and secure vpn, but have flaws with "whitelist" function (sometimes limits your internet connection speed with vpn's one)

good

Using Windscribe for years now, the only strange thing is that it sometimes auto-connects (even though I have it turned off). But their service is great and their newsletter entertaining, so I won't steal them a star for this (:
