BelifuDual Channel Tens Unit Electro Muscle Stimulator, Fully Isolated with Independent 24 Modes, Rechargeable Pulse Massager with Electrodes Pads for Neck Back Arms Chronic Pain Relief Body Building

I used to go to a chiropractor before I moved who had the EMS machines. I always felt great after because it loosened up my muscles and relieved the pain. After I moved, I had a hard time finding a chiropractor that had the EMS machines. I would go to a chain chiropractor's office and get adjustments. The pain would go away but within a week, I was back to where I was before and never felt like the adjustments were effective. I decided to give this machine a try without having any expectations that it would work. Boy was I wrong. I didn't think a battery-operated unit could be as powerful as the plug-in machines at the doctor's office but this unit is just as powerful. I found out the hard way when I turned on the machine and cranked the output. I had to unplug the connection because I almost fell to the floor. Another thing I like about the machine is that I can set a timer to as much as 60 minutes. At the chiropractor's office, I was limited to a 15-minute session. Yes, that was probably enough time to be effective but I wanted more. A con of the machine is the touch screen could be improved as I found it to be less sensitive and finicky. I also wish they offered a mode where the machine would stay on and give constant stimulation and have the stimulation gradually go up and down and so forth. All the modes seem to pause at some point. Maybe I just haven't found the right one yet. I highly recommend this machine as it has helped relieve my back pain tremendously which in turn, has helped improve my mood. When you're in constant pain, it's hard to have a positive outlook. It will also save you money on trips to the chiropractor.

I have to say I figured it was another gimmick that my Father was recommending when I said I had shoulder pain. He always buys things off the infomercials that never seem to work so I had my reservations. But I have to say this little older i-phone sized machine works. It really helps with soreness and pain that I get from working out and just generally pushing my self to hard. I hurt my elbow working on project so bad that moving it just shot pain up my arm. I put this on it a few times a week and sure enough the pain felt better and better each day along with mobility. And then working out really hard one day I re-injured my shoulder and sure enough it worked on that too. So I am now the one recommending a product. YIKES! Next I will be watching infomercials. LOL!About that actual product (Owned this product for over a year now)- they supply you with enough pads that it will be about a year before you need replacements if you use it all the time. Just keep them on the clear plastic after use and add a drop of water to them when they don't stick as well. The over all product is easy to use. Someone mentioned that it does have a lot of massage feature that is true but with all the selections you can absolutely find something that will work. If you crank the intensity up you will probably make yourself jump out of your skin so just take it easy at first then turn it up slowly until you feel it. Also the battery I have to say in mine is great. I use it all the time and it hold the charge for a very long time. I have put it on the shelf for a few months at a time and grabbed and it was still at the same battery level. The case is really nice because you can keep everything together and organized. The lock feature is really nice as well because I will put the unit in my pocket as I am doing things and it just does it thing. If you forget to lock it will change the setting so this feature is necessary unless you just sit there.

First, the good. It works well. It is easy enough to set up and start using. Seems to be plenty powerful. I have not needed to run the strength levels up past just over the middle of the range. I can recommend it, but there are a couple of concerns.The company's website where I registered the product didn't actually do anything at the time except thank me for providing my email and Amazon purchase info. I did finally receive a followup email a few days later. The "free" extra pads arrived by mail in reasonably timely fashion, as promised. I was a bit concerned because the company uses a ".CO" address. That's Columbia. The product is from China! The acknowledgement I had registered was a bit tardy. They don't seem to be using modern customer service software to track and provide feedback. However to date the product has proven good, and the customer service, while not light speed, is acceptable.Second, the build. The unit seems well enough constructed, but the case is made of a VERY slick plastic. Very difficult to manipulate without dropping it. Then there are the buttons. They are positioned in such a way that they are regularly pressed without intending to. Turning it off, on, adjusting power. The screen is also very sensitive and just putting it into a pocket can change time or mode randomly. UPDATE on this; there is a newer product manual which helps clarify the button uses and describes the use of a "lock" soft key on the front which address much of this concern.Then there are the cables. They function well enough but appear easy to damage. They have a plastic covering for the terminal contacts which fit very snugly into the case. Getting them in and out requires some effort. I have some concern that they may not last, and break if not handled with care. That said, I've been using the unit for about a month and they are still functioning as intended.Finally, is the very minimal documentation. What the various modes actually do is not explained. They are given a purpose (back, elbow, etc) or just a number, but the stimulation profile and pattern is not explained anywhere. UPDATE: a newer version of the manual is available as a PDF and addresses a lot of the concern. Still little info on the stimulation provided for each setting. Be nice to see a "wave form" diagram showing duration and intensity of stimulation rather than just verbiage. However the main shortcoming for me is that there is not any setting for just having it provide steady stimulation. That is a deficiency in my view, and the reason for 4 stars vs 5.It does work as it advertises and is quite inexpensive. The pads provided are good. I'm satisfied with my purchase, but wish it had an always on mode.Recommended.

Wow! This thing packs a PUNCH! It’s much smaller than my iPhone. I got it to help with my frozen shoulder and I think it will be perfect
