I have used these panels for the last 3 years and have been very happy with them. They are lightweight (20 lbs per panel) but sturdy. Their one shortcoming is that they only have a leg on one end which makes setup a two person job if your corral is freestanding. I have mine rigged so it attaches to my horse trailer at both ends and the panel at the end of the trailer swings like a gate. I can set it up be myself in 10 minutes. I also painted the panels white for better visibility.
