I ordered windows for the cottage with installation here. I chose it for a long time, because I myself once worked several times in window production in the capital and am a very picky customer)))
The price is not the cheapest, but also not the most expensive in the city. The same Visconda is more expensive, and for example, a similar five-chamber stack profile is 5% cheaper.
Deadlines - since I had 2 arched windows, the production time increased dramatically to 21 days. In fact, they were brought on the 23rd day. If standard windows are ordered, then the time frame is up to 7 days.
Quality - there are no complaints yet. Everything opens and closes well, the Seat fittings work fine, although I have a good opinion of the Vinehouse, but it was not in the assortment.
In general, winter will show the real quality of the windows, so if anything, I can change the rating and comment at any time. So far, I can recommend it, I liked everything. 9 out of 10 (minus the score for the lack of a Winehouse)
