VyprVPN and StrongVPN are two great VPNs that offer different features to their users. Both are priced competitively, and each offers a 30-day money-back guarantee. Vypr may not accept Bitcoin like Strong does, but it does allow for payment using email- an easy and fast way to pay for it without linking an account. As far as connections and speeds go, Vypr surges ahead of Strong with over a few hundred more servers in different countries when compared to Strong. VyprVPN also allows an extra simultaneous connection, Strong only allowing for 1. Strong may not log your IP address or use timestamps like Vypr, but they do have false claims surrounding the functionality of their product, while Vypr scores much higher in the ethics department. Vypr is also very secure, whereas Strong is a bit less so, but still offers good security. They both offer OpenVPN so that you can customize the product to your liking.
