I can see the usefulness of this project. Thank you for providing this tool. Can you please share some of the things that you've learned regarding these VPN service providers?
Here's something that I've learned: The VPNs that say they are the “Fastest VPN” on their website might be embarrassed by this. ExpressVPN, PureVPN and VyprVPN... I’m thinking of you.
There are a few VPN services claiming to be "The Worlds Fastest VPN" and paying people to repeat their claim. However the results speak for themselves. :)
