Customer Reviews

  • Author: Ted West
    I need something quick and easy to put in a generator enclosure, so I went with the Echo Absorber Natural. It ain't pretty but it works great. As soon as I lined the interior and put it over the generator it was like a whole different world. I'll be using this a lot more now that I know how great it works. Make sure you talk to Jim, he was really helpful.
