Editor's Pick: If you sit at a desk all day or just finished a workout, your shoulders, neck, and lower back can ache badly. Just attach the electrode pads, pick a mode, and relax on your own. TENS handles pain relief, while EMS works your muscles, so relaxation and DIY pulses each have their own uses. With 36 modes and dual channels, you can use it on two areas at once without interference. The 3.8-inch color screen has large, clear text, so you don't have to squint to adjust the intensity. The latex-free electrode pads are reusable over 50 times, and the 600mAh battery lasts a long time on a single charge, making it easy to take on the go.
