  • Performance 5 stars. LCD protector fell off.

    I have had mine 1 year. The thick transparent rubber like LCD protector developed air bubbles and came off. Basically there is the LCD screen. On top of the LCD a thin flat transparency sheet with black self stick that sticks to the black plastic around the LCD. On top of that is the thick transparent rubber like armor. Air bubbles developed in between the rubber and transparency sheet making the LCD difficult to read. I was able to rub each layer one at a time back into place. Personally clear hard plastic and epoxy will be the next fix once and for all. Basically buy this item cheap and good luck.

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

    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
    Verified Purchase

    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.

  • Great machine & price = Happy consumers
    Verified Purchase

    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
    Verified Purchase

    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.
    Verified Purchase

    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.

Questions & Answers

  • What is the pin connector size for these tens units? This unit does not specify pin connector size so I know if the electrode packages I already have will be compatible to this unit.

    • Hello Pgbuyer, thank you for your inquiry. Unfortunately, the information you have requested is currently unavailable. You will receive an email notification once an answer is posted. Have a great day.

  • Is the product has any warranty for something like - it just stops working after sometime?

    • Hello spiritualtechie, this does not include a warranty. Thanks for shopping with us!

  • What is the pulse width on this?

    • Hello kriali, the pulse width on this item is 30-300 uS, (10us/ Step). Thank you for shopping with us!

  • How much does the unit weigh? I did not see the weight in the Product Description? Is the size really 9 in. x 8 in. x 2 in. ? That seems to be very big for something to attach to a person's belt.

    • Hello overstockfan7, we have the listed shipping weight at one pound. Thank you for shopping with us.

    • Weight is not significant, does not weigh anything!

  • Why did you choose this product?

    • I chose this product because many years ago I had spine issues. I used to go to a Chinese doctor in Ontario, CA for treatments of the Tens Method for pain and cardiac arrhythmia issues. It was a blessing to me. Since then, I've not had another opportunity to get back to CA to see this doctor, but I miss the Tens for back pain/muscle pain issues. I was very happy to find this product here, and it's a great compliment to the inversion tables. I will most definitely let my Chiropractor know, so he too may decide if he'd like to try this on some of his patients.

    • highest rated TENS product. Hubby and I both have lots of knee and back pain.

    • wanted a combo unit

    • I purchased one for myself a year ago and i really liked it. My dad is having similar issues, so I am purchasing this for him.

    • I worked as an RN for many years. We used tens units for post-op pain. They worked really well. Now that I'm getting older and becoming more aware of aching joints I decided it's time for some non drug relief

    • seemed highly recommended and need something small for traveling...

    • Have one unit already, great unit.

    • I read the reviews and needed a second unit and the price was very reasonable.

    • I have used this unit and like it.

    • I loaned my TENS unit to my grandson. He uses it with great success, but I need mine back.

    • sounds like a great unit.

    • Family member had a stroke, his OT recommended this as a help to stem his arm.

    • Customer reviews.

    • Therapist recommended

    • Easy to use. We use it in our therapy clinics and highly recommend it to our patients. I have moved to a new clinic and I still prefer this unit to others.

    • I chose this product because it (and similar products by the same brand) was highly rated with many good reviews.

    • Our OT provider has gotten good review from current patients

    • recommendation from physical therapist for pain management

    • Husband recently suffered spinal cord injury and deals with considerable pain. This has helped in therapy sessions. I was hesitant to order from overstock again. Ordered a mattress cover that was supposed to be queen a number of years ago. It came in a package labeled "Queen size", but when I opened it, it was only a full-size cover. It was not my fault, was mislabeled, but I was still forced to pay a restocking fee to return. I vowed never to purchase another item from overstock and only my husband's injury and comfort could make me go back on that vow. I don't trust this company but will be willing to try another purchase to help him. I hope this experience does not go sour.

  • 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?

    • Hello KMS, unfortunately you are not able to do that. Thanks for shopping with us!

    • 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.

    • Each set of pads (2) can be set on different settings.

  • Aren't these units regulated by Federal Law to only be sold by a licensed physician? How can Overstock sell them?

    • We are still researching this and should have the answer shortly.

    • Hello Lee, thank you for your question. We have verified this unit is FDA approved, and can be purchased or sold over the counter. You may need to seek a prescription from a medical professional for insurance billing purposes. I hope this information is helpful. Have a great day!

  • Is it necessary to use ultrasound gel with the TENS?

    • No, it is not necessary. As long as the pads are new they will work fine without it.

    • no, they used to use dampened spongelike material with the electrodes connected to it.

    • 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.

    • No ...

  • does this item have a bag or a case with it?

    • Hello cchuasy, Yes, it comes with a hard plastic carrying case. Thanks for shopping with us.

    • It comes with a very useful hard plastic case ... I've even packed it in a suitcase, and checked it for air travel.

  • Which replacement electrodes work with this unit?

    • Hello, fenris7. Any universal electrodes would work with this unit. The ones that come with it are 2 x 2 electrodes, similar to the ones found on item number 15852229. Thank you for shopping with us!

  • what type of electrode connectors does this unit have? Pin or snap?

    • Hello theresasweet and thank you for asking your question. Model DS2200 uses the pin style electrode connectors. Please feel free to contact us again with any further questions. Have a great day!

  • 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

    • 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.

    • 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.

  • Which is the correct answer to: does this unit have 4 leads so you can maassage two places at a time? Overstock said NO; but next answer siad yes??? Confused.

    • 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.

  • does this unit have four leads for two spots at the same time

    • Thank your for your interest in the Twin Stim 2nd Edition TENS and EMS Combo Unit. I have found that the unit does not have four leads. Please let us know if we can be of assistance on this or any other issue.

    • Yes to this question. You can massage 2 spots at the same time.

  • 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?)

    • 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.

  • 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.

    • 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.

    • 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.

  • How does this unit compare to the TENS 7000?

    • 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.

  • Can this unit use an AC adapter? If so, does it have one in the packaging?

  • I am looking to buy a good TENS unit with muscle simulator having nice features and rechargable battery...Does this unit has rechargable battery ? Also, please provide the name of best TENS unit available.

    • This item takes a 9-volt battery and does not come with a rechargeable battery. As for which is "the best" that is a personal decision. You may find reading the reviews of the various units we have available helpful.
