Not too bad
First off, I have to say that I approach this type of device with skepticism. I didn't have any experience with TENS units before, but wanted to give this a try for some shoulder pain that I experience. The pads that come with the unit are very sticky, and easy to apply. I also did like the size of the unit, as it's extremely small and portable, and with a little practice, not too difficult to figure out. I must admit, my skepticism has been tempered a little bit, because I would find that after a session, my pain would be reduced. That relief lasted a short while however, as it tended to reactivate not that long after. However, I was expecting no results at all. From that perspective, I can say that there is something to this technology. I wouldn't describe it as a cure, or absolute relief, but it certainly can provide a measure of relief that for some people may qualify as invaluable. I think that the size of the unit is ideal, and makes it extremely portable. I will continue to use it in the hopes that perhaps with prolonged use, I can achieve better results. My initial experimentations with it have been more positive than I expected. From that perspective, I'll say that I was pleasantly surprised.
