The InTENSity Twin Stim™ III is a portable electrotherapy device featuring two therapeutic modes: TENS & EMS therapy, which are used for pain relief and muscle stimulation. The unit is among the upper echelon of pain relief devices, with a maximum output of 105mA, and it also comes standard with an AC Adapter and removable belt clip for easy, at-home use and convenience.

  • Relieve your pain by using the TENS Mode. 
    • TENS is a non-invasive, drug free method to control your pain by sending tiny electrical impulses through the skin. In many cases, this stimulation will greatly reduce or eliminate pain.
  • Strengthen your muscles by using the EMS Mode.  
    • EMS is widely used in hospitals and sports clinics to treat muscle injuries, to re-educate paralyzed muscles, and to prevent atrophy in affected muscles.

I have used my tens-pro a number of times now to alleviate pain in my shoulder and arm. I am so pleased with the product that I would recommend it to my friends and family, which I have. Thank you so much for such a good quality device designed to stimulate health.

This little unit does everything I wanted it to do at a much lower cost than the "loaner" unit I got through Medicare. When the "loaner" had to go back due to the end of my Physical Therapy (but not the end of my pain), I went in search of a EMS unit with similar capability. It works great for the muscle stimulation my leg requires 3-4 times per week.

TENSer
This unit is strong, has a nice auto shut off, and does relieve pain. Two reasons I give it 4 stars vs. 5 ....it beeps with each and every change as you set it up. This is a problem if you use it at night and sleep in the same room as someone else. Also, it is not user friendly....you must really pay attention to the manual (and even then it is confusing).

Pain Relief
I have been suffering from low back pain for months. Don't like to take too many pain meds. As soon as I put this unit on, it gave relief of the pain. It is wonderful. It is very comfortable. The only reason I didn't give it 5 stars is that it shuts itself off so much. I have it set to remain on continuously. Many times when I just turn it on or increase the intensity, as soon as I hook it to my belt, it goes back to zero and I have to reset it.

cranky back king
This little item packs a good wallop! Surprising battery life for the power it puts out. The stim units at my physio therapy office. Shut off before they reach a level that is strong enough for me.This little unit goes plenty high enough for even someone who likes the juice turned up. I am very happy with the product. And have already recommended it to others !

Outstanding TENS, easy to use
This is the first TENS unit I've purchased, and I couldn't be more pleased. I use it on my injured shoulder after experiencing the stimulation unit used by my physical therapist. The AC adapter allows me to conserve batteries by using the unit plugged in as much as possible.

TENS & EMS unit
I have experienced some relief from localized pain. The directions are very difficult to understand ( even when read by a doctor). Have no idea if there is a better way to use it since the directions are so difficult.

I have no complaints regarding my purchase. It took me awhile to get the hang of it since it is the first time I have used this type of instrument. Nevertheless, I was able to use it without any hassle. It is very user-friendly. It is a great buy!!!

Review of InTensity Twin Stem Machine
My husband and I like this machine, and we use it almost daily. We did find the initial instructions difficult and we had to call to see how to set it up to start using it. One we started using it, we have found it to be a quality product that does what is advertised.

Great item!
This TENS & EMS unit is working wonders for me. When added to my exercise routine and my medication I get a longer relief period from my local pain. The unit is compact, portable, and takes a bit of practice since the instructions are somewhat difficult to follow. The AC adapter saves on batteries and is a great addition to the entire product. Glad I purchased it!

the physical therapist recommended this product, and set it up. It is very helpful with the pain management and the nerve stimulator. Very easy to use and can be worn almost anywhere.

Love this device!
I feel like this was a great buy. I use it often in my shoulders and knees. There are a lot of settings and features I still don't know how to use. My only complaint is the complication of the settings on the unit. Fantastic buy, all in all. I do not regret buying this unit!

Gift
Gift for my brother. He is a firefighter. He has had pain in lower back and also rotator cuff surgery. He is a big guy and very muscular. He works out and runs. This unit has helped with issues that the chiropractor could not help. It has given him relief at times that he has never been able to get relief prior. Great product for anyone. Great value for the money. You can't put a price tag on pain relief, but thank you for providing a product that does what it does for a reasonable price!

Mr.
Wasn't sure about TENS when I was searching. One of my co workers swore by it for his back pain. So, I bought this unit. And the whole family loves it. It really did the job for me as well. It doesn't solve the problem if you have a chronic injury. But while it's on, the pain is gone! Feels great! Has a lot of thump for such a small unit. I figured only the A/C power would be strong...nope, strong battery power also. I have enjoyed this unit and would buy it again.

There is dizzying number of TENS, EMS and TENS/EMS units on the market. I select InTENSity based upon their time in the market and a record of continuously upgrading the product. I selected the Twin Stim III -- it has worked well for me in both modes. It was purchased for chronic back pain, it helps a lot -- it has also been used for very painful muscle spasms quite effectively. It has good battery life.

Receiving the product was very fast. Got it in 3 days. I had some issues with learning to use the product, but your customer service person was very professional in explaining the issues I had. I had a knee replacement and thought the TENS unit really helped to keep the swelling down. My husband has had some back problems and he uses the TENS almost every day. Overall... Good product and good service.

This is a great unit. My wife and I both have chronic pain issues and go to the chiropractor. I bought it mostly for my wife and she loves it. It has helped with the pain on several occasions in between visits. I would highly recommend this.
