Rodrick Confirmed Purchase
Nov 4, 2018
I have to say the product does work for insulation because of the extra air pocket. They are also well constructed and shipping was fast. How ever the only reason for not leaving a 5 star review is i purchased them for the need of noise reduction, unfortunately they do next to nothing in those terms. please do not take this as a negative review just be mindful if you plan on using them for noise.
