User Review: I got this upon a Youtube recommendation video. I have RSI from guitar playing / Computer work. My elbow was getting pain and I had noticed there was a swelling that grew. Doing my online research, I narrowed down the symptoms and realized I should try this item. Of course it's a rubber stick, but the tension and exercise method allows you to stretch your muscles a way that wouldn't be possible without it. Following instructions and methods on the videos, I used it for a little over two weeks. My Swelling went down!! I am happy to say all the pain is gone from the RSI and elbow area. It really works. The exercises are effective. I want to try the other strength versions of it if I get the RSI again. I am a professional musician and I can't be out of commission with those that depend on me. This was a life-saver. I recommend it for anyone with the same type of repetitive stress injury and swelling you get from over-exertion.
