Nope, they are real. Actually, these folks have taken an idea from the late 1800's and tried to modify it for today. There are old catalogs with these babies in there.
It's kind of like the "foal weaning halter" with mean spikes on the noseband. The foal tries to nurse and pokes the mare withe spikes and supposedly she won't let him nurse. That one is from the 1960's.
Thelate 1800's one is a horse is in a similar contraption but can only go in a circle. There are spokes from the horse going to a stationary middle. If you search you can find an old linotype pic. I can't link because I'm on my phone.
I love that they are saying it's a safety device, but not a single rider is wearing the most basic riding safety device: a helmet. Oh sweet sweet irony.
It looks heavy and akward, and I feel like if someone uses that thing to train horses with, they shouldn't be training horses. I understand their logic of keeping the rider safe (other than the lack of helmets...), but if the rider is that scared, I feel like a better option to using that would be to wear medieval style armor. Or just not ride.
Hmmmmmmph! To begin with its dangerous (can't even begin to list the ways it is dangerous). Secondly, a horse has to be about half broke to get him harnessed up and in there so how exactly is it desensitizing and training? And it is dangerous. Plus its is sheer stupidity. Did I mention it's dangerous.
Reminds me of the 'rebirthing' you see like on CSI and stuff where the 'therapist' wraps a troubled teen in a blanket and lets the fight their way out of the 'womb'. Some of those kids die (at least on tv).
Do not toy with the dragon, for you are crunchy and good with ketchup!
