The unit feels like a cheap toy
The packaging was very clean and professional.  When I opened it I noticed the product felt very cheap compared to models I had seen and tested in person.  Hoping for the best I tried it on a variety of areas, including foot, calf, back, and shoulders.  I tried different size pads.  The pads were fine, stuck well, pretty standard.  But the stimulation was not anything like the ones I'd tried in person. I've had recurring back pain, and when I tried one of these devices two weeks ago in person at a trade show, I had relief for several hours.  I had no such relief from this device. It just didn't feel or work the same.  Also, the settings are pretty confusing.  There are two insert pamphlets. One somewhat tells you what each setting is (they provide a list of the settings, I assume it's in order of how the display scrolls).  There is a separate insert in Chinese and English that is an acupuncture chart.  There is also one photograph in the first pamphlet that shows &#34;recommended&#34; placement (shoulders, lower back, etc) The images on the device are odd, one shows hands (ok, that's massage), the next one shows pinching, next what looks like a stomach (the organ, not the abs), a head with the brain showing, feet, and ears.  No explanation about why these images are the ones used (is the stomach setting supposed to do something for your GI?  No telling).  Bottom line, it felt like Chinese cheap junk, the stimulation was more like zapping the muscles than massage, and the intensity settings were inconsistent.  At one point I had to quickly turn the unit off because the leap between two intensities was so significant (from barely anything to pain in one setting change).  Perhaps mine was defective, but I'm just returning it and not replacing it.  Will look for a better model, probably not online, since I'd like to test it out first.
