Does not work... Used a few times in 10 months
I used a handful of times in ten months. Intensity does not work. I tried with one channel, 2 channels, 3 and 4 channels. Fully charged. Intensity does not work. I then plugged wires into a 4 year old tens/ems unit. Worries operate perfectly. Therefore, it's defective and junk. Quite a few people are complain about the same issue
