My overall experience with the noise cancelling inserts was very positive. The product was delivered on time, and as expected. They were simple to install and after 6 months of use, they are holding up well and look new. They biggest reason for the purchase, they do a very good job of reducing the outside noise in our bedroom. I am very happy that we decided to purchase them. Only downside is the cost. I spend close to $1,000 for two inserts. Still seems excessive. All in all, the produce performs as expected and we are happy with them!
