Overpriced, overrated gimmick - buyer beware! I had two window inserts installed in a room adjacent to a busy street in the hopes they would help drown out some of the road / traffic noise but have not noticed any significant noise reduction, whatsoever. In fact, the background noise somehow sounds slightly louder, if that's even possible.
Maybe if they actually worked, the 'used car' sales process and extended (2-3 months) lead times might be worth it but they do not. Do not waste your $ or time!
