I installed the product as described in the instructions and I also went to YT and watched a presentation/video. Customer was very happy. This was my first installation of this product and I intend promote it to my clients in the future. I think for me I will use a thin piece of material on the driveway surface as a gage to not put too much pressure contact with the Concrete. As the instructions mentioned that too much pressure could cause the garage door to open back up.
