Very happy with the windows and the price has been given by Sergey Vaganov and his follow up from the beginnning until the end. And we were very impressed with the two men (Vlad and Slava) installing the whole windows in one day. They did a great job and they clean after the instalation is done. As they are a busy company, we were very understable to wait 2 months until the installed the windows. Now we are enjoy our new beautiful sturdy and great quality windows specially in the winter time.
