Yes, it is a hand held tool that I have now been using for 2.1 week. Yesterday was the beginning of my 3rd week. There are 3 settings and you start out with the lowest gradually increasing each week to the next intensity. About mid week into my 2nd week I really started noticing a difference. The bumpy leathery feeling to my forehead is just about gone. My left eye is back to normal size and I can actually touch my eye lashes without pain. I am getting excited about the possibility of wearing mascara again. I haven't for 4 years except on a very special occasion and regretted it every time. A small thing, but as a woman not so small. I do not have the sharp electrical shooting pains now for days. Also just 3 weeks ago I could not be on the computer very long due to the light from the monitor & we have a new Dell flat screen, so it is up to date. The pain actually ranged from my left eye up my left forehead and through the center hair part of my head and all the way down the left side of my head. It is not an inexpensive device, but well worth it when you get such great healing & feel happy and without pain each day. This is truly a blessing to me and I know if it worked for me it has to for others. Like I say though it is not just for Shingles pain. It is for any kind of pain with the exception of cancer. The device comes with instructions and there are videos on line to watch for it. Please go to the web site that Hank B has posted. I do not sell these... I am only here as a witness to help all who suffer from pain and want relief without drugs.
