StimRx Units Offer Unparalleled Power


If you want real EMS POWER stay away from the low priced TENS units powered by low voltage batteries. They just can’t compare to the workout you will receive from our 12 and 15 volt POWER muscle stimulator units. Beware the cheaper battery operated Stim units that you will find on the internet. They are all Asian made and put out a very weak signal. Typically these inexpensive TENS units are a waste of your time and money. Most units that cost under $300 will leave you very disappointed and often breakdown after light usage. We sell only the highest quality TENS units and Electric Muscle Stimulator units on our site and fully warranty all units we sell so you can shop with confidence.
