    • Excellent product!!
I suffered a stroke a little over 2 months ago. While in the hospital, the Occupational Therapist used a machine similar to this one on my arm and hand to try to wake the muscles back up. It seemed to work, so when I was released I wanted to continue the same kind of electrical treatment. I asked my outpatient OT what they thought and they felt it was a good idea. I asked them which machine they would recommend and she said she needed to ask around and let me know. She is part of an email group with other OTs around the country, so she sent out an email blast to all of them to see which unit they recommended, and the majority of them all said the Chattanooga Primera TENS/NMES Unit, so that is the one she told me to get (I guess you could say that this product is the recommended choice of Occupational Therapists! ). Anyway, with all of that said, I couldn't be more pleased with this product! It is VERY easy to use and it has helped me regain movement in my arm and hand greatly! The unit comes with a very nice travel bag, as well as a very helpful booklet with diagrams which shows you the proper points to place the electrodes. It even comes with electrodes already in the kit, so there is no need to purchase extra ones until you need them! Everything you need is in the box. I was using it within 15 minutes of opening the box! The other great thing about this unit is that it is TENS and NMES! This is VERY handy (be sure to look up what the difference is)! I have primarily used it for NMES purposes, but recently needed to use the TENS feature and it helped a lot! This is an EXCELLENT product that has made a significant difference in my rehab! ... show more

    • Great unit and well worth the purchase.
This is a great unit and works perfectly. I was skeptical that a 9v battery powered unit would work so well, I’m glad I purchased this unit!

    • The professional therapist used this unit
Really love this unit. Was taking a family member to pelvic floor therapy for 5 months and the therapist was using this unit. She used it in the pelvic area, but also the back and hips. She was fantastic, but ended up moving to a different state. We bought one of these ourselves and just continued it self-administered. We had the advantage of watching the therapist do it first, but this unit is not difficult to use. And if you have questions about the different types of electrotherapies just go to YouTube for ideas. I chose this one because it also has the HAN TENS waves, which can be therapeutic for conditions like muscular dystrophy. Or at least it has been for my family member. ... show more

    • It does the the job and easy to use.
I am using the Chattanooga Nerve stimulate for my Methatarsoles in my left foot after Ankle surgery P13 and they do work in about 2 weeks (1 session daily) my nerves are almost back 60 %. The only thing I wish it had is an alarm when the workout is over and better pads. The pads that came with worn out very quickly they hardly stick after 2 weeks. The therapist ladie told me they should last forever. But they are not. Other way the machine is good enough and I guess so far good enough for me . Hope I can finish my recuperation. ... show more

    • Which is worse - My Knee or this Device?
This thing does not work. When I dial in the intensity, it just keeps going back to zero. Customer service said a few weeks ago they would replace it, but the tracking number says it hasn't even shipped yet. What's the deal?

    • Great unit!!
I have purchased for myself, gifted, and referred it to many. Easy to use, feels great, multiple settings, does both tens and names. I try not to pull the wires in and out or wrap them super tight. Wires are on the thin/cheaper side. Over time the plastic where the lead plugs in to the unit can break off and replacement wires aren’t cheap. If you take care of it the unit should last for quite a while. Takes 9V battery so it doesn’t die as quickly as some. ... show more

    • Good when it works
It is great when it works, but I have found it to be super sensitive to having the pads brand new. It works the first time I use the pads, but after that I have a hard time getting it to the 30 setting I need. I am going to OT because of my stroke, and I took it in with me. She got it to work only with the new pads. I don't know if mine is defective, or that is just the way it works. ... show more
