AMAZING!
I'm an avid backpacker and so, I workout 6 days a week. I get overuse injuries occasionally and my muscles are often tight. The Pso Series is amazing for these issues! I use it stretch out my muscles and get deep into the muscles, which I can't with my hands. Besides, my hands hurt right away if I try. This series works wonders and can be used in so many ways. I'm very pleased with the results! The key is great to take with you on trips, hiking, etc. They are fingertips without having to actually use your own fingers. I love it! Great way for a quick massage or PT session.
