My thoughts on B-Quiet

have used your product before so I know what to expect it is second to none. The product I used before had a different backing because i would have to stop and clean off my scissors this one doesn't gum up my scissors. I am actually not using it on another car, i am using it to sound proof my air conditioning unit on my RV and to help separate the intake and return air as the manufacturer does not do a very good job

Best Customer Service

I reached out to B Quiet for a shipping issue with FedEx. I received a call within an hour, and problem was quickly resolved. Very polite and professional. I was grateful such customer service still exists in today’s world. And a made in USA product. 100% happy.
