If you have no VPN at all, using 184.108.40.206 on your iPad or iPhone is a step up integrity-wise. It doesn't let you watch Netflix in other regions, but it encrypts your traffic and may even make your connection faster than other VPN services, thanks to a faster communication protocol.
They offer a premium service as well. It is called Warp+ and costs about 5 USD a month. You can also get extra Warp+ traffic for free by referring a friend to the service. Every friend you refer gives you both 1 GB of free traffic. Using the link below will give you and me an extra GB each.
