We bought this item to help up with recovery after exercising. We are in our late 40s but do a lot of sports (football, running, weight training, HIIT) and have noticed that we get more knots and aches and pains after intense exercises. We use a foam roller and trigger point balls but this gun is like the next step as it helps with blood flow and you can actually feel how everything loosens up after you use it, like when you get a massage. We specially like that has 20 speed settings so can accommodate intensity accurately. It is 4 people using it in our family (older teenagers do weight training) so it would have been nice that it had had a longer battery life (3 hours), but that is just because it is 4 of us using it daily. Overall very happy with our purchase, I am sure it will save us more that one trip to the physio
