Unfortunently I'll have to agree 1 vet I talked to it about said it's hocus pocus but horse people will do anything may as well load your horse up and drive down dirt roads. Talked o another vet who is a lameness specialist who actually has 1. He said the only reason he has it is because people keep asking for it and doesn't believe in it at all but it makes him money.
I have to agree I had one and sold it. It does increase blood flow for faster healing. But, like a friend of mine said if I want to get shaken to death I'll run the trailer on the drag strip part of the road for free.
