Review on ACU Point Electro Puncture Massager Pen by Myel Shuey

I have used this item to "reset" or stimulate the vagus nerve and it has worked well for that. Look it up in your favorite search engine. I have also used it on painful areas like knees and back and it has worked well in those areas. (also tried it for a toothache and it worked, but I've used it outside the mouth and I don't recommend it or give medical advice) I read a few reviews and some have had the pen not work for a long time. I really hope this one lasts a long time.
