Excellent device!
I ordered this mainly because my father wanted it for his body aches and I'd figured that I would try it out too. I wasn't sure of the strength at first or how it worked too well but boy did I find out. DON'T SET IT TOO HIGH, start low. It works wonders on myself because I always wake up with a stiff neck and shoulders. I recommend this item seeing as how I can save money from going to an acupuncturist and especially now that many places still are not open due to the state of the pandemic.
