## Customer Reviews

### ⭐⭐⭐⭐⭐ Use on any large areas of sheet metal to dampen resonance vibrations
*by  on Reviewed in Canada 15 January 2019*

This stuff isn’t just for automotive use. I assembled a new computer system recently and the combination of motherboard fan and a big 110mm case fan set up some vibration. Since computer cases have large expanses of mostly flat sheet metal, there was an annoying resonance setting up in the case. I knew exactly what I needed and this product solved the problem; I knew it would. Vibrations have been eliminated and the system is practically silent. Great stuff!

### ⭐⭐⭐⭐⭐ Excelente calidad

Excelente funcionalidad

### ⭐⭐⭐⭐⭐ It works
*by  on Reviewed in Canada 29 May 2019*

I used on the back of a rattling clothes dryer that was driving me crazy. One sheet tamed it I'd say 80% when it's cold but, as it claims, when the dryer warms up the product becomes more effective and complete absorbs the annoying sound. Excellent stuff.
