Belifu 4 Channel TENS EMS Unit – 24 Massage Modes & 30 Intensity Levels, Rechargeable Electric Pulse Muscle Stimulator with 10 Pads & 5 Lead Wires for Pain Relief & Therapy, Color Silver

I bought this tens unit a 1 1/2 years ago, when I was struggling with a variety of muscle aches. Now, 18 months later, after a minor accident yesterday (luggage fell from the overhead bin on an airplane and landed on me), I’ve got some aches and soreness. I’ve reached for this tens unit again, and again it’s delivering relief. It has withstood the test of time and a lot of use, and it still works like new.Much better than the store brands available at CVS or Walgreens, this can be customized for listing on the body, intensity, and type of stimulus, offering a truly wide range of options from gentle to hard pulsing, deep tissue stimulation.I think this is a terrific product and would buy it again.When I purchased it, manufacture offered an additional pack of adhesion pads in exchange for registering for the 24 month warranty. I did so, but was skeptical that I would have my inbox flooded with junk mail. I don’t think I’ve gotten a single email from them sense. My point is that they are not bugging me to death and abusing the use of my email address. It was an great exchange for me.

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.

This is the BEST Item I’ve ever purchased for pain!!! The 1st time I used it, my shoulder pain was a 9 on a scale of 1-10! Within 5 minutes my pain was down to a 4! By 15 minutes I had NO PAIN!!! Amazing!The directions are super easy to follow & the electrodes have better adhesive than my o previous tens, as the last TENS they fell off all the time. These Electrodes are on until You remove them! My therapist suggested leaving the electrodes on all day, just unplug them & plug them in again later!I was amazed! The adhesion by nighttime was as good as it was earlier in the day!Very Easy to Use, pick the body part you want to treat & pick the type of treatment & then turn up the intensity til you desire. As easy as can be & delivers exactly to that area what it needs!Plus it was Cost Effective! My first TENS had only 2 electrodes & this one has up to 8! Awesome! I Highly Recommend this TENS Unit!!!
