Just been shopping around for VPN's and Smart DNS services this weekend. Somehow stumbled across these guys, I had never heard of them before, but the price is right at the moment. They are currently allowing free sign ups for both their Smart DNS and VPN services, with no payment details required to sign up.
I have successfully tested the Smart DNS with Netflix USA and Amazon Prime USA. However, the Netflix streaming didn't work for me using Chrome, I had to use MS Edge. I assume it needs some static routes to block the Google DNS. Also haven't tried the VPN yet as I'm still playing with TorGuard.
I contacted customer service to ask when the the free offer would expire and I was told: "We don't have time frame for that. We will update our website once users are required to subscribe once the free access is over."
Note: This service simply allows you to unblock the geo restrictions, you still need a subscription to the service you want to acces, i.e. Netflix, Hulu, Amazon Prime, etc.
BBC iPlayer works seamlessly, looks good
