I will start by saying that I like most of chemical guys products.. I usually order straight from them but had to order a few other things from Amazon. I used this pad twice & by the time I was almost done the second time I noticed that my pad wasn't feeling right. When I stopped to blow it out I noticed that around the hook & loop ( Velcro) it was releasing. A line completely around the hook & loop. I have it paired with a 5in. backing plate on a Harbor Frieght DA.. It looked to me as if I had added to much pressure to the pad which wasn't the case. I can say that the pad did a wonderful job while it was a live :-). But didn't last long enough. I used air to blow out the pad between every other panel & after each use was sprayed & cleaned per chemical guys website. Maybe main was just a bad egg..
