There was some miscommunication on shipping between Indow and UPS freight which made for a frustrating delivery. Be expected for the delivery dates and times you receive from either company to not be accurate and somewhat variable. When opening the inserts, scissors are not strong enough to cut the bindings, would recommend a sharp knife. The inserts themselves are very easy to unpack and fairly easy to install. I only required additional help as my windows are over 12ft tall. There is some sound damping, but not sound proof. I would say decibels have been lowered by maybe 1-2db.
