I like Windows USA because they're really friendly and stay in touch through the whole process.
The installers were really personable, worked very hard to assure we were happy with their work. They represented the company very well.
During demo best part was ease and locking of window. I have to wiggle to get to locking (not one finger closing as demoed). Then there is play or movement once closed both horizontal and vertical. We're told could pick width of exterior mold but wasn't given choice. Also was cheap metal and looks like mobile home. Not very high end. Screen mesh not tight and flaps like flag in wind. I have had competitors window in other home and tons better. In retrospect I would have used them instead for this install. Price quotes were identical. Would not recommend.
