i work at a yard where most of the people there use one of these on their horses. A friend of mine has one and let me borrow it on my mare and i couldn't believe the difference. she is usually very tense but after having this on for 30 minutes she was stretching through her neck and really striding out from her shoulder. She was also lifting her tail more than i've ever seen her do before. so i am seriously considering buying one and just wondered what you all thought if any of you have one or have used one
