I love these things. They are great for home and automotive use. They are NOT up to the standard of a real road construction cone, but the construction cone is large, bulky and quite heavy. They are ideal for roadside emergencies and for marking spots in a yard or driveway for almost anything from a soccer goal to "protection". They are highly reflective and have a hole at the top for a small flag or fiberglass street sign. I use them to make room for a kickback to land in a safe parking lot at the bottom of the hill. These, combined with fiberglass road marking rods and terrain marking tape, create a cordoned off safety zone for me to drop the slash down the hill into the parking lot. Very happy with them, their versatility and foldable shape.
