Hardened steel shafts wouldn't be easy to cut, and a thief would need to cut both shafts to remove the device from the hitch. Insurance company approved which is the important thing to consider, cheap units generally are not approved by insurers as a legitimate tow hitch security device. Be mindful when buying a hitch lock that there is little point of skimping on a cheap hitch lock to secure a significantly priced asset! I do not see the point!

Easy to put on and feels heavy duty, would take a lot to saw through and to big for bolt cutters!

Great heavy duty trailer lock!

Excellent! 100% Recommend!!! Great fit, super secure, easy to take on & off. Being in Fl, I think this lock holds up well in rainy weather. Nothing is fool proof but this is some heavy duty security without breaking the bank. Speaking from experience, some of the pricey competition is not as secure as this one.

Simple to use. Hopefully it will deter a potential thief, but if they really want it.... There are other travel trailers in the storage unit without locks, so easy pickin's.
