Etekcity 4-Channel Rechargeable TENS Unit,FSA-HSA Eligible Muscle Stimulator for Pain Relief, After-Exercise Relaxation, Physical Therapy, 8 Electrode Pads, Back,Neck,Shoulder,Sciatica, Period Cramps

This is a great unit and it's very easy to use, it comes with three different sizes of pads, and you get two pairs of the medium pads, a pair of large pads and a pair of small pads. I have used the medium ones several times now and I have yet had to wash them, because the adhesive is still really strong. I would suggest using it on clean dry skin, (no lotion, etc.) and the pads should last a while before you have to clean them, I usually have a session with this after I get out of the shower. The only downside that I have against this unit is that there is no setting for a constant current. They are all pulsating, some longer pulses than others. I find it rather strange and I don't know if it works as well as the other unit I used to have a long time ago. It had one mode it was on or off and you could control the power level of the current. This one seems pretty strong as far as currents go, I have been using it on the medium setting, anything above that gets painful. So if you like to use the high settings on the units this will work for you for sure. The pulsating will take some time to get used to, I find that the cupping one is more closely to the old steady current unit I had. Don't get me wrong this is a great unit, and for the price it's well worth it, but if you're looking for one that has a steady current like the older models did, this one doesn't offer that.

This is a great little gadget. So many settings and seems to work well. I would recommend.

My husband and I both love using this unit. It helps me self manage pain from pinched nerve /bulging disc. It’s easy to setup and use. It has lots of pulse options which can be a bit confusing to select through. You can chose by body part which has preset pulse style or you can specifically chose a style like knead or tap etc. In the end after trying All the different ones I really only liked 1 of them , the one labeled neck because it’s a steady pulse. Could just be my sensitivity. Would be interested what others say. Just more of a personal preference so I did not rate down for that. Others may perfectly enjoy them. I like that I can hookup 2 separate connections -program A/B at different intensity and you can put up to 2 connections on each of those. So total of 4 stimulating pads at same time each with their own intensity setting. So often I hook up 2 On program an and my husband will hook up one on program B and we can each have our own intensity setting because he can handle much more than I can. on program a and my husband will hook up one on program B and we can each have our own intensity setting because he can handle much more than I can. have to try each one to see what you like. It also comes with different size pads so you can use in smaller or larger areas of body. I use large ones on my low back or IT band and smaller ones on back of neck or shoulders. So be careful to read about correct placement as there are a few places not to put them like around carotid artery. Comes with a nice little storage bag To keep all of the Parts from getting lost. Sometimes I throw it in my purse to do it in the car when We’re headed off on a long drive with the RV. The charge last a really long time so big points for that. I’ve only had to charge it one time since original overnight charge. Make sure you give good charge first time. You do also have to be sure to connect the pads to device before stating the current. If you try to place or remove on your body while it’s running you will get a little shock. Nothing dangerous but it stings for sure. Overall for money good value and does what I wanted.

Nice unit. It works, but when treating the lower back you have to stick four pads on your skin at the right location, which I can’t do on my own. So using it became a bit of a chore. It is good for stimulating the muscles and the units display is clear. It doesn’t have a touch screen which was a deliberate choice for me. Instead it has buttons for each feature and intensity. I had deduced a cheap unit with a cheap touch screen would be an unnecessary incumbrance. This device is easy to use and cleverly induces the sensations of tapping, massaging and vibration. I ended up getting a vibrating belt and are using that instead as it is a lot more convenient. Either seem to give similar levels of relief.

This unit works great. I get complete relief when using for back or neck pain. I like the fact I don’t have to take medication for aches and pains. I just use this unit instead.

This little unit is very powerful and holds up well. It's the only one I could find that let's you use 4 separate lead wires. Nice that it's small and portable, but powerful enough to really help. Felt just as good as the professional unit at the chiropractor. Easy to use.

We have several athletes in this house and this thing has become a game changer for wrestling season and tournaments. Working on getting everyone their own pad set to make it easier to manage. This little thing is powerful!!! Also pretty easy to use.

Purchased for my daughter and she loves it. Really helps with back and muscle pain
