Review on Discount Ramps Guardian DH-PB-5: Heavy Duty 36 Inch Rubber Parking Curb for Maximum Protection and Safety by Aaron Richardson

We put one of these (36") in our garage and none of my cars move with it. It's on the driver's side for the front wheel and stays put on every time except when my kids kick it like a big toy. We drive very slowly towards it, because who wants to run over someone? To give you an idea of the cars that don't have this problem, we drive a slightly understated Benz sedan, a midsize SUV, and an upscale Jeep Wrangler SUV with 33-inch wheels. We were concerned that the Jeep would roll over slightly, but that wasn't going to happen unless we intentionally pressed the accelerator harder.
