Tens Unit Handheld Electronic Pulse Massager

This electronic pulse massager is nice but could use a bit of improvement. My husband tried it out on some lower back pain. He is prone to muscle spasms. He said that when comparing it to other tens units he has used in the past, this one does not have the intensity he would like to have. Even setting it on the highest setting he didn't feel it was as strong as other units. I would like to see it come with more then 1 set of electrodes. The gel does not remain sticky for too many uses so you will quickly find yourself having to buy another set. They aren't all that expensive but it would be nice to have more then 1 set when you first make the purchase. Also I feel the buttons should be backlit so it would be easier to make your selections. There are several "pre-programmed" settings that are useful if you want to try a variety of settings. The dials that turn the intensity up are exposed so they be easily moved or bumped, adjusting the intensity even if it was unintentional. That could potentially be bad and painful.
