I didn't know what to expect of the EMS since I've only had TENS used on me before by my first chiropractor. This little, low-cost unit is deceptively powerful and effective! I strongly advise you to follow the guide closely and definitely give yourself a few minutes at lower settings before increasing.I got this unit after researching using TENS for lower leg circulation issues. Here's what I found:Local Blood Flow: Studies have shown that TENS, especially at low frequencies (e.g., 2 Hz), can significantly increase local blood flow. For example, one study found that low-frequency TENS increased local blood flow by up to 40%. This effect is thought to be due to the release of vasodilator neuropeptides (such as substance P and CGRP), which widen blood vessels and further promote circulation.Practical Application: For lower leg circulation, pads are typically placed at the back or front of each ankle, allowing the electrical signal to pass through the muscles and circulatory system of both legs. TENS is considered safe for regular, even daily, use and can be helpful for people with mobility issues or those at risk for circulatory problems.I'm not making medical claims, just sharing what available research yields.The pads are quite comfortable and stay on if you don't move around too much. I like it's portability, so I can have it at work or on the train during my commute. It's a convenient size, about that of a later generation BlackBerry.

This device is amazing! I’ve heard about muscle stimulators but had never tried one until now. I struggle with a 25 yr old lower back injury. Recently while packing to move homes my l back was really flaring up. 800 mg of ibuprofen wasn’t helping at all. I finally tried this device running a lower back preset for 20 minutes and wow, my pain was gone. The relief is fast and lasts quite a while. My second time I paired the same preset with some Aleve tablets. I was pain free all day. This thing works so good I just bought another one and some extra pads. Great little device!

Great product works really good highly recommend.

This unit is affordable and easy to use. The unit does provide excellent pain relief and can be worn while you do daily necessities.

Great for EMS and recovery.

I've had a few of these things but this one is buy far the best I have tried

It's is hard to maneuver, the directions aren't clear. I would buy something more simple.

Love this because it’s a tens unit and ems. Ems feels amazing for my back pain. Confusing to use so read the booklet. I just wanted to dive in and use it right away but I didn’t know how to use it really until the second night.
