I ordered windows from this company. It is true that it is better to pay for quality once than to pay for repairs later. That's why I chose windows from the German profile. After reading about companies selling plastic windows on PMR websites, I chose this company because they are the only ones who make windows from high-quality German materials. The price corresponds to the quality! I ordered windows from them and I don't regret it. There have been no problems with windows for many years! Thanks for the good work. I recommend this company.
