  • 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

  • Works good
Color: Black
Tens unit works great! It’s lightweight and small so it’s convenient to carry with me anywhere. I use it for TMJ pain and it works great. It’s easy to use with lots of settings and intensity levels. I had it for about a year before it stopped working. I reached out to the company and they were so helpful and quick! They sent me a new one and it arrived very quickly. Would definitely buy from them again! ... 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

  • Nice Product, Good Value
Color: Black
A very thoughtfully put together product - nice drawstring bag to contain it along with the pads, little velcros on the cords to make for neat storage, several cord options. I found it to be effective for stimulating muscles around my knee... pain gone.

  • surprisingly helpful for easing my sore muscles
Color: Black
I’ve been using this Belifu TENS/EMS muscle stimulator for a little while and it’s been surprisingly helpful for easing my sore muscles after a long day. The unit has a good variety of modes and intensity levels, so I can adjust it depending on how much relief I need. The pads stick well and the battery lasts longer than I expected — overall, it’s a solid affordable option if you’re looking for an at-home pain relief tool. ... show more

  • Magical but will not charge
Color: Purple
I purchased this item back in November. I dont use it often but when I do it does the job every time. I love this little tens device so much i would buy it again and again but......this machine will not charge to save its life. I have tried numerous times with numerous different chargers and it still wont charge. Obviously the battery life is amazing to last all this time using it as needed. I just wish it would charge because I dont wanna have to buy a new one every time I wanna charge it because the battery died. ... show more
