One of the best free VPNs. I've been using it for several years. Of course, there was problems, but they are fixing their problems very fast. There are some free servers, the free usage time is 15 minutes, but you get used to it very fast. This app provides you with excellent speed for free, and you don't have to complain about time limits. You won't find another VPN that consistently provides such free service for years. Excellent speed and stability. I recommend it.
