Just signed up for 2 more years with AirVPN. Yes, there are other higher-rated services, but AirVPN always works perfectly and is reasonably priced. I run it on Windows, Linux, and OSX, which does limit the contenders. The main usage is secure browsing when traveling and file transfer. I like that it uses OpenVPN and also that it is NOT at the top of the list. OpenVPN is very secure and with a lower rating is unlikely to be a hacking / DOS/government target. I could go on about great AirVPN is, but really, it would be like telling you how much I like my water or electricity utility. It just works and I don't think about it more than once every two years when I need to renew my subscription.
If you are a journalist, dissident, researcher, blogger, commenter, troll (LOL), etc. this is a VPN to seriously consider. It's well respected within those circles. Works with TOR as "VPN over Tor" and has settings to make this a bit easier, but does take some level of skill to set this highly anonymous (and potential attention-drawing) configuration up. Many of the advised VPNs DO NOT work with TOR in "VPN OVER Tor mode (Your VPN connects through the Tor network not vice-versa). This is not your "regular Joe consumer" VPN. It's for folks with far more to do than watching videos and playing video games. The server selection is more than enough to move around the globe.
AirVPN is by far the slowest VPN I have ever used. Whichever protocol and/or server I have used, it didn't make any difference. My internet speed decreased by over 90%, download speed as well as upload speed. When you take a look at the AirVPN forum, you will notice loads of users are experiencing the same issue, for which AirVPN obviously has no solutions.
