This accessory is very convenient. Works well with Just Dance and Yoga Studio games! But most people want their hands free for a fitness box, which doesn't work if you're carrying it properly. I've found that carrying the controller on your palms (pictured) instead of the back of your hand works great! I went from 42 to 25 years old and registered 90% of the hits. Technically my hands are still free and I can make a fist. It's not the most comfortable device and the material isn't breathable so your hands will sweat with intense exercise, but it works as intended. Matches Joy's cons exactly. You didn't fly for me. It works for what I want and that's all that matters.
