I'm not trying to kill Sales with PD-Proxy but i have also purchased previously for a month and PD-Proxy only works for 14 days or so. further their price is not the best as they do no support OpenVPN protocols YET, and even TCP Connections are still buggy which they said they would fix last year. if all that is fixed then pd-proxy would be great!
If anyone else needs help with a free or good premium vpn service, don't feel afraid to contact me! i'll help
