I did not have a good experience with Carri-Lite corrals. They are fantastic for traveling but when you extend the collapsed legs to put the panels up to full height, it leaves a 2’ high void from ground to the first rail. My horse (14’2h) put his nose under the rail to check out the grass next door, lifted his head and discovered he could quite easily move the (very lightweight) panels. After he got them out of their stronger circular shape, he was able to maneuver a couple of panels down and walked right out. All within the first 2 hours of try-out in my pasture. I will say no panels broke during his escape.
I did follow all instructions, used the pins correctly, etc. After the first try I supplemented with bungees, orange construction netting, etc., but it ended up being such a big hassle I gave up on it and was able to sell it to a woman who had one and loved it. So I guess it just depends on how much of an escape artist or “grass is always greener” type horse you have. I replaced mine with a high-tie and that suits my horse much better (and is much easier to set up).
