Negative Positive
Title: Flimsy at best
Review: I purchased these wheel chocks to keep my trailer in place on my driveway, which they actually do quite well as long as you also use the donut to stabilize the trailer jack wheel. Unfortunately I made the mistake of not removing them one day when I moved my unladen trailer with my truck. They provided nearly no resistance to the trailer and were completely flattened. My mistake, I know, but I didn't expect them to be destroyed. Now I'll be fabricating a set of chocks out of 3/16" plate steel in my garage.I'll still use the donut.
