Review on MAXXHAUL 50019 Rubber Wheel Chock, 2 Pack: Optimal Tire Safety and Security by Adam Webbie

These rubber pads are too hard and above all too smooth. I was trying to block my RV in my driveway and I knew right away it was going to be bad when I put the blocks in (I bought 2 sets) and they started sliding on the concrete! It's serious, like they're on ice all the time, even when it's 102 degrees Fahrenheit outside on a concrete surface. I kept walking and trying to use them thinking they were supposed to stick and my pendant started to slip. No way. these come back. Very dangerous!
