Bests & Worsts Reviews from Amazon

The complaints with this product mostly center around its inability to lay flat after being shipped tightly rolled up. I had this problem at first too (I had the beige concealer). I was a bit fed up but thought perhaps a little bit of heat might help loosen it up. I had cut it into two 3 foot sections to use at different doors, so I got on my hands and knees at the first door and used a hair dryer to gently warm up the rubber. It seemed to work but was taking forever, so I grabbed both sections of the cover and tossed them in my bath tub. I let them soak in very hot water for a few minutes, and pulled the first one out, which felt pretty limp like a noodle. I drained the water off (gave it a few swings to clear the water from the channel) and laid it on the floor to cool off and dry with some heavy items pinning down both ends, same with the second. The heat "reset" the rubber a bit, and letting it cool while sitting flat locked it in nicely. Since then, both of the covers have worked flawlessly. Using wide strips of 3M double sided foam tape has helped keep them very flat and very much locked into place.
