ComfytempTENS Unit Muscle Stimulator for Pain Relief Therapy, FSA HSA Eligible TENS Machine with 24 Modes and DIY, Dual Channel EMS Unit, Pulse Muscle Massager for Back, Shoulder, Sciatica, Knee

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.

Works beautifully! I've had it on for the last 2 days straight and I feel like its helped a lot

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.

Product is working as described. I had a hard time comprehending the instructions, maybe because I've never had a tens unit before? Once I figure it out, it's been working great. The adhesive pads stay sticky, even after multiple uses. The product is durable and the batteries last quite a while. Powerful little machine

Helps with dizziness

Very effective

This tens machine shockingly works. It shocks and pulses you like you would expect. It comes with a bunch of pads that are very sticky, which is good. The downgrade in rating is the setup for the machine isn’t user friendly and the instructions are not great. All in all I would buy this again, it does what it is needed for by takes some fiddling with to get there. That being said it was cheap and the pains in operation are to be expected for a cheap unit.

Very good highly recommended this product super cool price very good too
