The local company I ordered Amsco Windows through was great, the installation went well. The price was fair. Energy efficiency and noise buffering is greatly improved over my old windows. That is why I am giving them 3 stars. But the windows themselves are such a disappointment. Every window has impurities between the panes making it impossible to get a clean window. These impurities range from broken glass sometimes embedded in the seal, squeegee markings, and, creepiest of all, noticeable finger prints preserved forever between the panes. I contacted the company I ordered the windows from and they did replace one section of one window - the new one also has impurities including some fingerprints. I was made to feel my expectations of clear clean glass unreasonable.
