I had tried a cheap (around $30) TENS unit to see what it was like and wanted a step up. This unit is perfect with up to 4 electrodes, and the BIG improvement - it can be plugged in or use batteries. I don't usually walk around when I am using it so the plug in feature is great for me. You will want to get some aloe for the electrode pads as they dry out, and you will eventually want to order more, but 4 is plenty to start with, and the treatment options are diverse enough to provide different kinds of relief.
