Review on Rechargeable Waterproof Electric Scalp Massager - LANDWIND Head Massager with Two Kneading Modes for Stress Relief, Hair Growth, and Relaxation by Chelsea Hunter

I've been looking for a head massager for a long time. I'm glad I got these. Relieves my headache quickly. The overall design is pretty cool and feels comfortable in the hand. It is so comfortable to use and I use it to massage my neck, shoulders and legs. Pressing the power button toggles between two vibration modes or no vibration. I have found the vibration mode to be good when I have a bad headache. I usually use vibrate mode. The battery is really useful. It will turn off automatically a few seconds after you stop using it.
