My Physical Therapist recommend a TENS unit and this model. He showed it to me on AMZON, taught me how to use it. I also found the videos on Amazon very helpful. The on/off power level buttons are a bit small for me, and I have some difficulty with programming, but I see my therapist tomorrow and he will help. Great price and product.
It was very disappointing to see charger works only on 110 Volts.While
Today most of the chargers works on Universal Range 110 - 240 Volts
Bought Carex Travel Pack at Walmart. Opened the first packet, wipe was dry, like it was never hydrated. Opened a second, dry. Opened third, fourth, all dry. And I can't return them as half of them are missing from the 10 pack. Not a Walmart problem. Won't buy Carex products again. Zero quality control!
A little heavier to transport into and out of vehicles but hopefully more reliable on uneven surfaces .
Love it! Right on time! Very comfortable in your own home.
