I have been in pain for 15 years and had 8 surgeries which helped some. I have used 2 other tens units along with physical therapists using professional tens units. This unit has been the most successful at reducing pain. The variety of signals to choose from allows user to select one that feels comfortable and is effective.
The price is very affordable and the cables are durable. Have accidentally snagged the wires while moving and none of the cables have failed. Would recommend to others
