Very nice massage gun that comes with a different variety of heads you can exchange on it. There are different vibration settings that you can use as far as the speed of it. It has a digital read out to tell you what setting you are on and, what the charging power is at. Works all the nicks and crannies right out of ya in no time. Charging holds for a long time so, don't have to continuosly recharge. Feels so good on your back, neck ,etc...Definetly, worth the buy!!
