    This is cumbersome, has enough wires to entertain a dozen cats, and did nothing to relieve even minor pain. Don't waste your money!

  • good price

    Will use it when next shoulder surgery needs physical therapy where they use a tens towards the end of sessions, very unique tool, haven't needed it as yet, but remember it was a great part of each therapy session!

  • Great Multi-Purpose Investment

    After dealing with some aches, pains, and pulls from triathlon training I stumbled across a TENS/EMS system that did a great job of eliminating these issues without getting "doped" up on meds or spending a fortune with my doctors. The TENS/EMS I was originally looking at was about $$$$, so I started looking into good names/brands, reviews, and more affordable options. This system met all the requirements and I got the system today. I've been like a kid with a toy on Christmas day - I have used it on my calves, lower back, upper back, deltoids, biceps, hip flexors, and abs. I'm loving it. It's relaxing, loosening up my muscles, and fairly easy to use. I HIGHLY recommend watching some video tutorials on YouTube and reading the instruction manual, otherwise you'll be one of the review up here giving it 1 star and talking about how it drives you crazy. It does require some know-how, but I got up-and-running in under 20 minutes.

  • Helps my tennis\iPad elbow

    Yes, there is a new medical phenomenon called iPad elbow. At first I thought I hurt my arms lifting some bedroom furniture, but that was months ago. The arm braces helped a little, but did not cure anything. I saw this set and purcahsed because of the good reviews. Everyone was right. Take the time to read the manual so that you understand the difference between TENS and EMS. Whatever mode you are in, once all your settings are up, you push the up arrow to increase the intensity to a point that is comfortabnle to you. That is how you "START" the device. For the life of me I was wondering why it was all programmed but wouldn't start pulsating. This device pays for itself after missing 3 PT deductables. If you plan on using this a lot, you may end up needing to buy some extra sensor pads.

  • This Works - Get your pain relief here

    I purposefully held off on writing a review until the newness factor wore off. This works as advertised and has a couple of neat features. I go for physical therapy somewhat regularly due to my condition in my shoulders and neck. This product does everything the therapists product does, plus a bit more. (She even help me tweak some of the settings). Extra bonus, this has the A/C adaptor so you are not going through batteries like crazy. This is perfect for home use. 4 pads means that you don't feel lacking (i had previously tried a 2 pad). The pads have lasted for between 6 - 10 uses of a half hour in duration. The directions are easy to follow and use for the settings. Nice that it comes in a kit and everything can be kept together. Bottom line - the product really works well. I have had no issues and at this point have had it for almost 2 months.

  • Excellent deal and fantastic product.

    I found this to be of high quality and easy to use. The instructions are very easy to understand and using the unit is very simple. I picked this Intensity Stim lll over another websites product costing more but doing basically the same as this unit does. I find it to be a great value for the money. Plus the pads are of high quality and last a long time. Does a fantastic job of helping to relieve muscle pain in my arm and shoulder area. Very lightweight so if you want to clip it to your belt or put in a coat pocket, etc. the unit is easy to take along with you wherever you go. Its even small enough to fit in your shirt pocket. The a/c adapater is a great plus for using it at home and saving battery life. If you are thinking of getting one of these for your pain management then I highly recommend this unit. High quality unit, very well made. I give this 5 stars.

  • Great product

    I actually got this product for a relative with lower pain pains and he hasn't tried it yet so I don't know if it will help his back pain. I tried it on myself just to make sure it works before shipping it overseas and this little machine does an amazing job relaxing your muscles. I tried on the different settings and different intensity and was very pleased with the product. The product arrived within two days, I was very surprised since I got the regular overstock free shipping.
