Query: Great product shipped at warp speed

I was really pleased with the amazingly fast shipping. I knew what I was getting in the product as I have been using the body blade in physical therapy after shoulder surgery, but now my insurance is saying "good enough" long before I am healed. I can't buy the big machines but I can get this. It provides a great tool for shoulder rehab. I'm not doing a lot of the exercises on the chart yet - ok I tried two but I had my own exercises from my therapist. I can't speak to prevention or strength training, but it's a great tool for shoulder strengthening after surgery or injury (but I would suggest at least a consult with a PT or other appropriate health care provider to make sure you're on the right track if you have injured yourself).
