Problem with USB power supply. TENS unit worked as expected.
This is a credible TENS EMS product, with a variety of patterns and a very good range of intensity.<br />I wanted a portable unit that I could put in my backpack or sports duffle, so I could deal with achy muscles after sports or doing odd jobs away from home. This unit fits that bill admirably.<br />The TENS unit is solidly constructed, not too heavy but with enough heft to give it substance. In other words, it doesn't feel cheap or like a toy. The display screen is nicely sized, so viewing the options is fairly easy. There are basically 6 modes, with each having 4 iterations. A and B channels are independent, which allows you to alter the intensity of each channel. While not usually mentioned in these portable TENS units, you can also opt to just set up one set on a channel, for a simplified 'massage' instance.<br />The setup of the pads is very simple and straightforward. The setup of each channel, selecting the modes and intensities is fairly intuitive. I'm not sure if my prior experience was a large factor, but setting up the channels and actually using this unit seemed very easy and less complicated than previous generations of portable TENS products.<br />I did have one issue with the product. The USB power supply was faulty. After connecting the power cables, it failed to charge the batteries. I simply used another usb power brick to charge the TENS unit.  I will need to test the provided USB power supply to determine if it's truly defective. I will update this review after I determine the actual condition of that component.<br />After an afternoon of biking and playing some tennis, my leg muscles were barking, especially the calf muscles. So, while at my friend's house, we were both recuperating from being weekend sport warriors, and i pulled out this product, to attend to my leg aches. He watched with amazement and curiosity. After a brief session, he asked if he could try it. So, I set it up on his balky knee, and adjusted the pattern and intensity. He said it's fascinating and effective.  I told him I have a set at home, and got this for my 'away' bag, and explained the science/technology behind the TENS EMS. Told him I got it from Amazon. He wrote down the name of the product and said he needed to get one, too. So, that is a random, objective endorsement, which I feel positively influences the rating.<br />Attached are photos to show real world images, with ruler for size reference.<br />I feel the product matches exactly with the description and illustrations in the product details. It is decently priced in the market niche. Based on ease of use, and quality of build, it merits 4.25 - 4.5 stars and a high level recommendation.
