TENS 7000 Digital TENS Unit with Accessories

Works well so far, having tested multiple settings and intensities on my leg and foot. It appears effective so far for stimulating my leg where I need it. The leads are a good length such that I can hold the device in my hands while the pads are attached to my feet. I ordered the battery unit instead of the rechargeable one base on other reviews that the battery one has better intensity, and so far I find the intensity to be pretty good. The battery has lasted through several one hour sessions so far without showing indications of dying. However, as another reviewer noted, my "new" unit I received appears previously used. The electrodes package was already opened and the pads were displaced on the plastic backing, indicating they were previously removed then placed again. The lead wires were unwound and crammed back into the unit in a tangle. The battery was already placed inside the unit. While the unit appears to function as advertised, it is unacceptable to receive a "new" medical device that is previously used, especially one that sticks to the skin, and has necessitated that I purchase additional pads to replace the used ones I received, and will require an earlier replacement of the battery.
