I have ben with SolVPN for more than 6 months. Their service has ben the bst so far. I have tried other VPN providers in the past as well, but ever since going with Solvpn it has been great. Truly open and unblocked access, even P2P services. They only offer OpenVPN VPN connections which also work across office proxy's and firewall'd networks.
Their network speed is excellent and support is excellent too. Pricing is among lowest for OpenVPN service. I recommend them highly.
