I registered at your website and downloaded the configuration file given by your system on your website. I can confirm that it, indeed, works just fine. The speeds are a bit on the slower side, but that is to be expected from a service that is being provided to the user for free.
I only tested the USA location so the experience might be different for different servers depending on which one you choose. Everything seems to be running fine, however, and even though the speeds aren't that great, the latency is actually pretty low compared to other VPNs I have used in the past. I will report back if I find out more.
You might experience a better speed by using UDP as using the TCP protocol for a TCP based application can result in double performance loss.
We will eventually upgrade our servers to provide a faster connection for our users. Thanks for the feedback!
I will be trying out connecting through UDP instead of TCP soon, although I am not the biggest UDP fan. I did use the VPN recently again and I was utterly surprised by how much lower the latency was compared to other VPNs. I know it is not a matter of location, as I am comparing this to similar VPNs near the U.S. Whatever it is that you are doing in order to keep latency to a minimum, it is working wonderfully. I have yet to try out VPNs at other locations, but I don't expect anything different. We'll see how that goes. Is there any ETA on when you plan to go paid?
We still have some minor issues we are trying to improve, these are both server and client related. There will be paid plans in the very near feature, can't give a reasonable ETA yet but we will keep you updated.
