My wife had been walking around with a shoulder injury that would not go away. After months of treatments (physio, massage and you name what else) the problem was finally solved, for a short time, because not much later our dog suddenly pulled hard on the leash, and yes, the injury was back. Good friends had been talking about a device that would offer red light treatment and that the recovery would be faster and permanent. So of course we Dutch are somewhat skeptical but also curious. It turned out to be a short story, because after a few days(!) the injury disappeared like snow in the sun and never returned. Because of its deep effect, the PowerCure Pro does more than an average physio treatment. We immediately bought the Pro and saved a lot of money (and hassle). Highly recommended if you are really looking for a solution.
