They made us buy these in school, but they are awesome, I would recommend though that you buy the handle that takes batteries, my problem is I got the one that is lithium ion and seems to be dead everytime I want to use it.
The design is great very easy to find and look in the eye. It makes everything you see very vivid and helps look for the conditions you are looking for.
I tried getting into this technique but found it to be lacking. I am sure that there are very good doctors practicing this technique, but I like fast results and it seems that I get fast results with the diversified technique along with gonstead, ART, Graston, and taping.
I love using kinesio taping on all my athletes, but still dont like the fact that most insurance companies view it as experimental. The recovery time on sprain is really reduced.
I love using Graston in my office with all of the athletes and believe it or not a lot of my medicare patients. It works wonders on frozen shoulders. I would recommend Graston and ART together they work hand in hand. It is worth the money.
