ZONETECH Security Wheel Clamp Chock Lock

I bought this after several Home Depot trailers were stolen in our neighborhood. It was easy got "install" ("Install in quotes" because all I did was unlock the prongs, put them around the tire, press in and lock. As my Son would say, "cinchy") I was concerned that it would be way to slip it off by turning to a side but the prongs are large enough to prevent this. Ands the tires will only turn half a turn, at most I love the yellow and red paints. It is clear that they are present. I gotta believe this serves as advertised - as a deterrent. I like the lock merchanism is protected with a cap. And that one key fits both locks. Again, great product at great price. CORDIALLY, FORD, DRIVE ON!
