Bought my first set a year ago and have used them for every holiday since at the entrance to our property. Thus far they have withstood daily traffic from regular vehicles and trailers (our car & truck, UPS, FedEx, and Amazon box vans) and infrequent commercial vehicle traffic (Power and Telco long reach bucket trucks, fully loaded with gravel dump trucks, propane tanker half full, and more frequent traffic from my tractor with impliments). Only one has shown any signs of deformation, this being a slight bend to the cable cover. I highly recommend these for the price. Just bought a second set. They will hold up. I store them in a barn out of the weather and sun when not in use.
