I began looking into magnetic therapy when I discovered my dog had hip and elbow dysplasia - many vets directed me to bioflow - but being me I needed to do my own research/homework - that’s when I came across Trion Z - their site was very informative - but I still did some more research before deciding that Trion Z really seem to be up there in magnetic therapy. I took the plunge and ordered and am not disappointed with their products or their service.
