Your review: I have these made my auto repair shop for noise protection. They go under the ramps for my drive on rack so that when the ramps pivot and slam down, these padded mats make it much more quiet. In this industrial setting they last a long time.
Pros: These pads get a workout through hundreds of cars per year and have to replace every couple of years. They should last a lifetime if they are used for working/standing on as normally intended.
