ProtonVPN has the unique distinction of placing no data restrictions on free users. You can browse as much as you want, as long as you want. You will be limited to just one device on the service at a time and can only choose between three server locations, but the unlimited data makes up for all that. It doesn't hurt that ProtonVPN, from the same people that brought you super-secure ProtonMail email, is very concerned about security and customer privacy. For all that, ProtonVPN is our Editors' Choice for free VPN.

Another VPN with a money-back guarantee is CyberGhost. The theme we were seeing here was that when servers are good, they're really good, but when they're bad, they're really bad. However, after looking through Reddit threads, we're not really sure how this ranked in the top three. The biggest thing: This is not the VPN to get if you're looking to torrent or stream, as it's known to be pretty slow. Reddit user NewWorld98 writes: 
HotSpot Shield is a product that has had some ups and downs in terms of our editorial coverage. Back in 2016, they picked up some very positive coverage based on founder David Gorodyansky comments about protecting user privacy. Then, in 2017, a privacy group accused the company of spying on user traffic, an accusation the company flatly denies. Finally, just this year, ZDNet uncovered a flaw in the company's software that exposed users. Fortunately, that was fixed immediately.
