Pretty good, but there are a couple of issues...
The VPN starts out very fast, but the speeds start dramatically decreasing after you use it for a long time. There is also an issue in which the VPN will accidentally reconnect after you press the disconnect button. If these issues are fixed, I will gladly give this app a 5-star rating!
12/12/15 Update: The app sometimes automatically and spontaneously disconnects from the server. The disconnection never occurs in a consistent manner. This has been a prominent, recurring issue ever since I updated to iOS 9.2. I do not know if this is just an unfortunate coincidence or an actual compatibility issue. Either way, the disconnection issue causes very annoying data leakage. It is especially annoying when I am streaming videos and music. Please fix this! If disconnection cannot be fixed, then at least add DNS leak protection, so that nothing can load outside of the VPN tunnel and nothing will load until the app reconnects to the server.
