This device is the real deal. Frankly, I was quite skeptical despite the supposed science. And the price seemed high for an LED device. But the truth is I've tried all kinds of approaches to reverse arthritic problems in the fingers of my left hand, including medications, dietary supplements, and general dietary changes. I quickly got away from nsaids because their side effects are well known. Plus, I also felt lousy taking them. The only thing that offered some relief was a supplement called Universal Flex. But that was limited.
