Bests & Worsts Reviews from Amazon

I have bought and used Noico and other butyl based mat on my car doors. This Killmat is not as sticky as others, even if it is heated by hair dry or heat gun. Handling is relatively easier because it is not as sticky. However, how good this Killmat stickies to the metal is questionable. It is very important for the mat to stay sticky to the inner metal of outside door. I will check after this winter to see if the Killmat still stays to the metal. So far Noico has been effective to reduce road noise when applied on the doors. I do not have as much confident in the kill mat. Doors should be the first area to treat to hear or measure difference. With a phone app, the measurement can be done before and after on the same stretch of road with same speed, which is better than human ears. I have used half of 36 sqft package. However, I wish I can return or replace with Noico. Compare with Noico, I recommend AGAINST Killmat even at current price differences. I regrate purchasing this Killmat !!!!!
