While the San Andreas Massage Gun produces up to 3200 pulses per minute with its powerful motor, it remains muted. With its ultra-quiet brushless motor, you can have the comfort of massage while travelling, or working in the office without disturbing those around you. There is also a built-in 5000mAh power bank so you can charge your mobile device with a USB cable. Small in size, tectonic in function, 3 different percussion speeds provide a perfect massage experience with gradually increasing pulse frequency. Comfortable to hold, strong and ultra-light, the vibration generated by the device does not cause any discomfort to your wrist.
