I bought the lifetime offer for 20$ during black Friday. Unfortunately, it's not working properly. Many locations can't be connected to with the Android App and if it's possible the connection is leaking the IPV6 address or even IPV4 is not working properly. Further, it's very slow, not as the name would suggest. After contacting customer service through chat, the issues couldn't be resolved. I wanted to use the money-back option they have stated on their website. It's been nearly 2 months I haven't received any money back, even after several emails. Unfortunately, I have to say that this VPN Provider is a scam and not recommended.
This VPN is not connected in Iran using their proprietary software. Additional software such as Cisco and OpenVPN should be used. In peripheral software, a third of their servers do not connect, or if they connect, the speed is so slow that you regret using it. This VPN is not suitable for use in Iran and China with strong firewalls. If you buy using digital currencies and are not satisfied with the service, they will not refund the money. I hope they solve the problem related to Iran and China. Otherwise, my suggestion for others is not this VPN.
I have been using it for about a year and now it is very bad, with slow connections and the application for Windows disconnects itself and no longer connects. I was unable to connect for 3 days through the Windows application. I also made the native Windows connection (manual setup) and did not connect, in various protocols. What works well are browser applications (Chrome, Firefox). They connect fast and have good speed. I had to subscribe to another service (PureVPN, which I used before).
