I'm not real impressed with it. Whatever floats your boat , I guess. I'd make sure the horse had solid training as far as ground work and under saddle first.
Some of the popular trainers march around moving a horse here and there "at liberty" so..... but if I tried that my horses would probably decide they would rather work from the other end of the pasture. Basically, I'm just too lazy is what it boils down to.
