Review on Xprite Wheel Stabilizer RV Tire Stabilizers Locking Chock for Campers Travel Trailers Trucks with Built-in Wrench and Anti-Theft Combination Lock, Adjustable from 2'' to 10'' - Pair by Mark Holloway

This item was purchased to replace regular wedges. When trying to remove one of the tires, I couldn't move the ratchet in any direction. I've tried several times and checked twice to make sure I turned the ratchet correctly. Finally, extra muscle was added, and the two support rings that hold the ratchet in place clicked. Now the ratchet did not contain the gear. Upon closer inspection, it turned out that these rings are made of cast iron. I removed the rings and ratchet and used a couple of channel locks to remove the device. Bad quality, not recommended
