We ordered these because I urgently needed 20 cones for a large promotion in two days and that's all I was able to get so quickly. They are very good but a bit small for commercial work to mark where construction is taking place while the trailers pull in and maneuver around the property. With Tropical Storm Dorian circling we had some 40-60mph gusts and they blew a bit but under normal conditions they were strong enough to withstand normal winds. - They're a good size for private vehicles, a bit smaller than trailers, but LED lights help with that. They come folded up and in a zip bag which will be nice when we're done with this work as the boys can literally stow them in the back of their trucks should they need them for other jobs in the future.
