Review on 🔌 Electric Pulse Neck Massager with Heat: Intelligent Neckology Massager for Effective Pain Relief - 3 Modes, 15 Levels, Cordless Deep Tissue Trigger Point Massage - Portable Neck Relax Massager for Women and Men by Debbie Dixon

This electric collar is very similar to those used in physical therapy. Pretty comfortable both in wear and shock. It moves the current up and down the electrodes, so it's like a shiatsu massage. You can adjust the strength. In contrast to Shiatsu, this makes the neck muscles ache a little the next morning, but brings relief. Also, unlike shiatsu, this thing is very compact and can be used sitting or standing at the table. In general, the thing is good.
