  • This TENS unit is perfect for at home & travel.

    This tens unit is everything I expected. A very portable, easy to use device. It can be used with a single lead (2 electrodes), or with 2 leads (4 electrodes). The timing and pulse parameters will be the same for both leads if using both. You can adjust the intensity independently. You will want to purchase extra sticky electrode patches. I found them online and also at my physical therapist. Best price for extra set of 4 sticky electrodes runs about $2.50. You will get one set with the unit. They measure 1.5" square, but you can use 1.25" round or square for this unit. Depending on your skin and cleanliness, one set may last daily use for 1 week. I'm still learning about this. You won't be disappointed with this unit. Good value for the money.

  • Great quality for the price

    I suffer from alot of mid back spasms and neck pain from a severe car accident a few years ago. I've tried everything from P/T to massage, chiropractic, and nutritional therapy. I've been getting these spasms that last 5-6 hours at a time several times a week during flare ups that nothing seems to touch. This unit had greatly reduced the severity and length of the spasms. I don't go anywhere without it and even sleep with it turned on when needed. It's very easy to use and I like the TENS vs. EMS option. The construction is better than the last unit I had, I especially appreciate that the clip is metal as I keep it on my belt when I'm wearing it and I don't have to worry that it will break. Would definitely buy this unit again. Only cons which I did not indicate in my rating as I feel they are more personal to my situation than the unit itself: Make sure you try different shaped pads, the ones that come with it where too small to spread the current out enough for my pain management. Also I was really hoping I could use it on my neck also but it does not help the pain there.

    • How did the image on site compare with the actual product? Great
    • How accurate was the on site description of the product? Great
    • Please tell us about the quality of the product. Had to exchange my first unit because of an issue with the channels but 2nd has worked very well
  • Great machine & price = Happy consumers

    I injured my neck and shoulder a year ago transferring one of my patient over to another bed and since then my back has never fully recovered. I occasionally still experience pain, especially on my neck/shoulders. My physical therapist at that time recommended that I purchase a TENS unit but that brand that they're recommending literally cost an arm & two legs (approx $700?). Well, to make long story short... I searched online one night for TENS unit and ran into this machine w/ lots of good reviews and with a price that won't burst my wallet. I was hesitant at first but decided to give it a try since the price was reasonable and I have to say... I am glad I made that purchase! Machine works great and worth every cent. Also, what more can you ask for? It's a 2-in-1!

  • Great for a paralyzed person

    I am paralyzed and have tried cheaper stim units and they just didn't work well. This unit works great and can create a strong contraction on muscles that haven't been voluntarily used in nearly 4 years.

  • I recommend this product and this company.

    The product arrived very quickly... before I expected it. I used the product extensively to help heal a pulled hamstring. My hamstring healed a lot faster than it would have without the EMS. A couple weeks later my brother borrowed the unit for a similar situation. He also had good results.

    • How did the image on site compare with the actual product? The product image on te site was identical to the actual product.

    Had to go to a local medical supply store and get larger pads, but other than that, I am pleased. In a short time, it has relieved muscle pain on three family members. Great purchase!!

  • Works good

    The product works great for my back. Very strong, I barely have the intensity level turned up. Lots of options and variable patterns levels to chose from. Glad I bought it. And my wife likes it also.

  • A good buy!

    I'm a physical therapist and i find this item very useful to treat chronic muscle and joint pains. The only thing i don't like about it are the small electrodes that come with the package. But I bought new pairs of extra reusable electrodes that i can use with the ultrasonic gel so i won't have to buy the new sticky ones over and over again. But I can say, this is a good buy for it's price and most of my patients like it, too.

  • Ease to use

    Easy to use. The instructions are clear. Had to look up pad locations on the web. It has enough power for the average person. Do yourself a favor and bet some larger pads. The 2" squares that come with and not adequate.

Ask a Question

I understand the unit has two lead wires and each lead wire can use two electrodes (pads). However, can each of the two lead wires be set on separate settings so that I can attach two pads on my knee with a low setting and two pads on my hip with a high setting? KMS on Nov 23, 2014

Hello KMS, unfortunately you are not able to do that. Thanks for shopping with us! overstockcustomercare1 on Nov 25, 2014
 
Yes. You must place two leads on your knee and the other two leads on your hip. Then adjust the settings to your needs. I own this unit so I know. needrain on Dec 20, 2014

Answer This Question

No, it is not necessary. As long as the pads are new they will work fine without it. jmgoverstock on May 1, 2014
 
no, they used to use dampened spongelike material with the electrodes connected to it. rusty925 on Jul 8, 2014
 
If your pads are not sticking just wet them, shake off excess water, let stand for about 20 seconds and apply. Also keep them refrigerated in a sealed bag when not in use. They will last for a couple of months. dorothy2014 on Aug 15, 2014

I see you can buy the replacement pads at other sites a lot cheaper... why are they so much at Overstock? Can you recommend buying elsewhere? How often do they neeed to be replaced? Thanks mariburr on May 17, 2013

Answer This Question

Thank you for your question mariburr. We cannot speak for other sites. As far as the replacement pads, if stored properly in the sealable pouch, at room temperature, these self-adhesive electrodes should last for 8-12 uses each. Have a great day. overstockcustomercare1 on May 21, 2013
 
I don't know where you are finding replacement electrodes for a lot cheaper. Overstock has the best prices for replacement pads that I have found. warren8r on Feb 10, 2014

Answer This Question

Thank you for your question mariburr. The Twin Stim 2nd has two channels and comes with two lead wires which can be used simultaneously. Each lead wire uses two electrodes. In other words, it can be used with two electrodes or four. I hope this clears things up. Have a great day. overstockcustomercare1 on May 21, 2013

Can you tell me if the EMS will actually contract the muscles (as opposed to just stimulate them)? I need a unit that will do the muscle contraction for strength and re-building, as well as TENS for pain control. (Is the EMS the same as NMES units?) 45flathead on Nov 19, 2012

Answer This Question

I'm sorry for the delay in answering your question. I finally received the following answer: Electrical muscle stimulation (EMS) and neuromuscular electrical stimulation (NMES) are two names for the same thing. Devices that have this functionality do contract the muscle and are often used for the purposes of strength training and muscle re-building. overstockcustomercare1 on Nov 29, 2012
 
 

What are the dimenstions for the actual unit, not in the case? The description suggests that the product is 2 inches high x 9 inches wide x 8 inches long. Looking at the photo, it does not look like the width is only 1 inch shorter than the height, so I wonder if these are the dimensions for the product in its case. I would like to see if it will fit in my pocket. Thank you.  on Oct 9, 2012

That is the measurement for the case. The actual product is 1 x 2 1/2 x 5. It looks quite small and I think it will fit in most pockets. overstockcustomercare1 on Oct 11, 2012
 
It's 4 x 2.5 and 1 inch deep. Fits into the pocket very easily, there is a clip on the back as well. tab132 on Mar 30, 2013

From looking at the specs, we would say they are quite similar. This unit has a little more adjustability and range, and also has the EMS modes which we think makes it a slightly better machine. overstockcustomercare1 on Aug 13, 2012
