I have been using this provider for several months and I am fully satisfied with it. The customer service is fast and productive. I've had a problem at the beginning of our partnership, and it was solved very quickly. Also they have a wiki, that was useful for me. The price is great, it would cost me twice the money or more for the same vps in my country.
I won't be lying, there were minor periods, when the service was offline for me. But the company always posted about the problems in the twitter and I wasn't in a panic, that I did something wrong. It was fixed very quickly, so it isn't a problem for me.
My general impression is really great. This company fully satisfies my needs plus more. The RAM burst is very useful and really working. I wish that they will be online for many more years.
