The Hyperice Hypervolt Percussion Massager is a premium handheld massaging device. The Hypervolt uses percussion therapy to relieve muscle soreness and stiffness, improve your range of motion, promote better blood circulation, and accelerate warm up and recovery. So the Hypervolt has a super powerful, high-torque motor to actually get to work on your muscles, so you would think that this thing would be super loud then right? Nah. The Hypervolt is actually pretty quiet so you can do your thing and not really bother anyone around you. 

Now it is fully connected for automated use with the Hyperice App.
