I'm editing my initial review since I ended up placing a second order. My first order was delayed multiple times. Some of the delay was due to supply chain issues, but then they planned a warehouse move and forgot to factor that into shipping times. The inserts themselves are high quality and I still think they are the best out of the options I explored. The team members that I worked with were great. The noise reduction is good but I did hope for better. Part of my noise problem is low-end highway noise, so I wasn't too surprised when it wasn't as good as I had hoped. The seal that they create is huge for energy efficiency though and that is a big part of why I returned to cover the rest of my house. I timed my HVAC system before and after install and saw a significant reduction in the amount of time it took to cool one floor.
