I wonder how long it would take Sierra to break it?
That's always my first thought whenever I see some kind of cool, potentially-useful "gadget." Buy them Jolly Balls and pasture toys and stall toys and they'll just push it into a corner and poop on it. Buy something that might actually make YOUR life and horse-keeping job easier, and it's quickly dismantled, bent, cracked, and basically FUBAR.
