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.

Product is ok, directions for use are very poor and difficult to understand. Does not address starting a session properly, and it took me a long time to figure out how to turn it on.

Cost-effective!
I bought this product after having been diagnosed with shoulder impingement. I use TENS for pain management, and EMS for strenghtening muscles around the shoulder. I have benefited appreciably. My physio confirmed that the parameters in a pretty acceptable range, and they do not have to be as sophisticated as their devices' have. I would recommend this product. I could add that the pads last more than 10 uses as long as they are applied over a precleaned skin.

It works for me!
In the several weeks that I've owned the "InTENSity Twin Stim III Digital TENS & EMS Combo Unit" I've found it to be a very useful and high quality device. However, a few weeks after I bought it, I also bought a "Twin Stim Plus 3rd Edition - 4 Channel Digital TENS, EMS, IF & Russian Unit" and if you don't mind spending the extra money, you also get "IF" which I've found to be quite a bit better than just TENS alone. I highly recommend both units. The IF offers more pain relief than just the TENS but it requires at least 2 channels (4 electrodes) in a cross configuration, so depending on the location of the pain, you can't always use it but in most cases you can still use the TENS. If you have pain and haven't tried a TENS and/or IF unit... what are you waiting for?

I have chronic shoulder pain due to impingement and tendonitis, with occasional flare ups in pain. After using this product a few times my pain has been greatly reduced. The effectiveness of this TENS unit is comparable to what was used on me during physical therapy. I especially like that you can adjust the pair of electrodes independently with regard to intensity. I also chose this unit because you can both use AC power or batteries. This saves on batteries when I am using the unit at home while sitting on the couch.

Intensity TwinStim
This TENS unit has provided me with substantial relief from radiculopathy associated with spinal nerve compression. While it doesn't cure or completely relieve the discomfort, it does reduce it and make more tolerable. It is not a treatment, but another pain management tool for my toolkit. 4 stars, rather than 5 because it took me a bit to figure out how to use the settings; the instructions could have been simpler.

End User
Very satisfied with my tens unit. Wall adapter connection to unit seems a little fragile but works fine. Be sure to wash and dry your skin where you intend to place electrodes so they will stay on correctly. When you peel the electrodes off, pull near the wire with a slow steady pull. Once off wipe sticky side quickly with an alcohol wipe, let it dry then place back on the plastic sheet. This will extend the life of the pads.

I have been using the TENS unit on a daily basis. It helps the pain because I do not have to use pain medication, so it is working. Also, the only thing that I do not like are the pads because some of the sticky glue seems to come off the pads every time it is used. Otherwise, I am very happy with this unit.

Owned for one month. Use plugged in, no battery. Purchased to help with chronic rotator cuff problems due to weight lifting, and for occasional back spams. The unit seems to work fine, and as expected. Through stretching, and other therapeutic exercies, I have not doubt that this unit is contributing to a more rapid recovery. For the price of this unit, I have no qualms about buying it or another like it.
