  • Pros/Cons * UPDATED 2026*
Color: Gray
The Belifu Tens machine is an amazing little tool to have when you have a muscle/tendon/bone injury. Similar to what you would recv during a PT session: it’s compact, easy to use & definitely provides relief. Why the 3 star? I herniated 2 disk in March of last year…while on journey to recovery I purchased the Belifu Tens machine (June 2025) - in less then a year it has just stopped working. Disappointed that a product like this would be thrown away in less then a year - however, due to the relief it does provide (when working) I will purchase another & Hope it’s last a little longer. Review Update: 2026 Customer service - 5 🌟 Star! I Was contacted by Belifu Customer Service recently . They advised they had reviewed the above & wanted to resend/refund the Belifu Tens due to defectiveness (stopped working after less then a year! ). I accepted refund & immediately repurchased the same. I Can not stress enough how well this little machine works to stimulate sore/injured muscles & joints! My fingers are crossed that this one will last longer then the last one (less then a year🙁) - IMO: Belifu Customer Service has gone above & beyond in refund & I could not be a happier repeat customer. I look forward to my new Tens arrival. 🤞Will update on the Tens Belifu longevity! 🤞 ... show more

  • Great Product, Even Better Customer Service!
Color: Black
I absolutely love this TENS machine! It works perfectly and provides excellent pain relief. It is easy to use, reliable, and quickly became part of my daily routine. After about a year of use, my unit unexpectedly stopped working. I contacted customer service, and I was genuinely impressed by how fast and helpful they were. They responded right away and promptly sent me a replacement unit with no hassle at all. It’s rare to find a company that stands behind its products with such outstanding customer support. The machine works great, and the customer service is even better. Highly recommended! ... show more

  • Oh It Stimulates to a T! Oh It Stimulates to a T!
Color: Black
This machine does perform some really intense stimulation. And really relaxes your Nerves and Muscles. But also upon my short experience just now while demo'ing for yall. I tell ya! Be "Really Careful" and work on your comfort levels because it can get painful if you set it too high. Common sence told me to start off low though. My muscles were relaxed and became low in pain after about the first 20 minutes on a comfort setting level 2, UNTIL! I attempted to demonstrated a higher level to yall. I had to redo the video. Man!! It wasn't nice. I couldn't even hold the camera anymore. So be very careful with these machines. And as it instructs us in the Guide Book. Talk with your Dr. "First". I was being a little hard headed just to share how it woks with yall though. I do have an Enlarged Heart, Lots of Nerve damage (Peripheral Noropathy), Rheumatoid and Ostio Arthritis, Slipped Disk in my Back, Plantar Faciitis in Feef, Severe Cronic Pain from bad and burst Vericos Veins, Spasms in Neck from Spinal Stenosis and Surgery. So yeah! im a Big Mess. And lot of the time im in crying 😢pain. So looking for any SAFE Avenue to relieve any and all of these issues. God knows of course what I and all of us are going through. And yes Prayers are always in my everyday for everyone. But He answers and performs Healing on His own time. I dont claim it But its there. And I feel it is ok to find plausible legal remedies to ease these pains that pull us down and cause suffering. So again this is so far a good solution for my pains, and could be for yours too. But I still will see my Dr. Before using it again due to all I have going on in this here body of mines. God Bless, try it out and take care! ... show more

  • Pure excellence at a very reasonable price!
Color: Black
Wow, the fact that you can have your own personal muscle stimulator that is similar to the chiropractor is super! This really does as it says it does, and in fact, when I pulled a back muscle, after icing and applying Arnica cream, I got right on this Tens EMS and noticed a difference right away. It truly does offer quick and effective relief which is very appreciated. The Blifu Tens EMS is quick and easy to adjust, lightweight, fitting easily in a pocket or even an apron. It has plenty of cord, and the battery lasts long too with a pretty quick recharge time, and I think it looks pretty slick. I use it with the Spectra 360 Electrode Gel and they work really well together. I highly recommend this fantastic product!!! ... show more

  • Redirects pain signals and exercises muscles efficiently.
Color: Black
This little unit is powerful and easy to use . I loved another unit and had 3 of them in the past , then suddenly they disappeared from the internet . Unavailable .. therefore , I needed to find one similar to it. They are hard to find . Many just don't have the ability to curb the pain or exercise the muscles at all . This one is adequate , has a long battery life and the pads can be used from any snap on type . I like it ! Hoping it lasts , many units breakdown either screen issues or on/off switch falling off .the build on these is often cheap . That's why, when I find a good one , I stock up! ... show more

  • Learn to use it. You’ll love it
Color: Black
Take the time to study the directions. I initially returned the item as the directions were not clear. The machine is used on Thoroughbred race horses. My help needed something simpler. The company contacted me as they were concerned, they sent me another unit and asked me to make an honest effort. I did, the unit is awesome, works perfectly, now that I’m comfortable with it I can instruct my employees. I make each one try the unit on themselves before putting it on a horse. This way they feel what the horse will. They both love it. Not only is the unit top shelf, the company truly cares about its customers. Very refreshing. Take the time to learn to use it, gonna love it. ... show more
