### ⭐⭐⭐⭐ 







  
  
    Good adhesive and very pliable
  

*by T***S on Reviewed in the United States on April 25, 2022*

Item shipped on time, the material is very pliable conforming to any shape under the door trim making a airtight seal improving Speaker presence, specially in the low end.center foam helps reduce vibrations on the door panel, it helps, but not entirely needed (if your car already has noise dampening.)
