Definitely worth the price. I live at a busy cross-section, speed limit is 35 mph, cars will usually spin out ,screech their tires and travel in excess of 50 mph. Easiest way to describe the windows performance would be that I no longer hear cars or midsize trucks go by. Screeching tires, vehicles that are modified to make noise are now reduced by about 65% I’m no longer shuttering every time any vehicle blast past my house. I’m able to sleep in this room with my head next to the window without any issue. It is allowed me to be in my living room in peace and without distraction. I would definitely recommend this product fortunately no other windows in the house have this noise problem otherwise I would purchase a second if needed.
