Doesn't work as well as my TENS unit
Quality product, well made, like the ability to detach and control the neck massager with the remote. Fit my neck fairly well. Why I returned it and only gave it a 3 star rating was that even as recommended by the mfg. wetting my neck, the different modes primarily just provided an electrical needle shock with little to no thumping. It did provide a good amount of heating and although I only used it twice the battery appeared to easily provide ample power.
