I approved it once for my daughters big eq horse. Trainer swore by it, other trainer not so much. Vet gave it to him. He did seem more comfortable and I then proceeded to retire him! Very expensive, but did make an improvement. I just didnt have the heart to keep campaigning him.
Results will vary depending on what the problem is.
If you can confirm there is no soft tissue injury then you would probably get decent results. But as mentioned in the link its an expensive crap shoot. I'd heard how wonderful it was in Europe and frankly feel thats part of the hype to get us to spend $$$ to try it.
The horse we used it on had many problems in the foot. It did help, but did not resolve everything. We tried many, many other things until I finally accepted that the poor horse just was going to have a forever problem
