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.

Great little machine, works great and the hand held controller feels very durable. I tried my wiring from my old Tens controller that has snaps and it works perfect I have a bunch of pads left over, so when I run out of these pads that come with this one I will change over to my old wiring and use all of my snap ones

I’ve used this a couple of times. It does provide temporary relief. Battery life is good. (You don’t have to keep charging it).

It works perfectly as described.o
