If you want real EMS Power, stay away from cheaply made, low-priced TENS units. They don’t compare to the workout received from our high quality units. Cheap battery operated muscle stim units put out a very weak signal and are a waste of time and money. Most units that cost under $300 will leave you disappointed and often breakdown after light usage.
Customers love FlexTone muscle stim units because they are high quality, backed with a 3 year warranty, and give you the TENS & EMS experience you are looking for. These are the strongest units available anywhere. It’s the last stimulator that you will ever need to purchase.
