Great for easing muscle tension

Arrived quickly in a nicely packaged box. Inside are three pink silicone cup and what feels like a satin bag. Since they arrived I have been using this on my shoulder as I have a rotator cuff injury. Since having an operation last year I find the muscle gets very stiff and feels tight. I've felt a real change since I've started to use these cups, the muscle feels less tight and gives me a greater pain relief than I've found in using hot & cold therapy only. Highly recommend.
