Been using it for couple of years. I have an unlimited plan.
Bought the VPN Unlimited lifetime plan with some big discount. At first I thought that there's nothing to loose with a proposed price and it is always good to have a spare VPN at hand when needed. But I was really surprised about the service. Connection speeds, user support (although I don't need much of it but used it couple of times), choice of server's location. Everything is good and better than average VPN providers. I have tried a lot of them like CyberGhoust, BlackVPN, ibVPN (this one is good too), NordVPN. To my humble opinion VPN Unlimited is one of the best! I use several slots on different devices (mobile phone, PC, router, pfSense) and they can work for months without the need of rebooting and connection losing. The privacy concerns? Well, there are no VPN providers that will keep your data safe if they have a warrant. I'm absolutely sure that EVERY VPN provider keeps all the logs of all your connections. So you can't get 100% privacy while using bought VPN. You just have to keep that in mind. With time VPN Unlimited dramatically improves their application with new features added. So I can't say anything bad about that company.
