We used these for our regional FIRST Robotics event, and they functioned perfectly, even with heavy robot carts rolling over them all day. Maybe not as high-traffic as some larger public events, however, they are very heavy duty, and hard to imagine them failing in all but heavy commercial use, which we don't think they were designed for. Also, considering other cable covers in this class can cost as much for one as these cost for a 3-pack, you can't beat the price.
