Ah, but here's the rub, an initial cash outlay. It ain't cheap to be this cool. A five wire controller, with five wires, all wired up, ready to go, will set you back the better part of a hundred dollar bill. The controller has an on/off switch and a small button that allows you to scroll thru the many different flash patterns. You can get a two or three or four or even a one channel setup if you want to save cash, but I wanted five channels to make a rainbow. Lots of places sell these. Measure your waist and add 6 to 8 inches to that measurement. You want to be sure that the wires will go completely around your body AND THEN SOME. (extra is fine) The in stock measurement was 48", which was perfect for me, but you can order the wires any length you want. I also saw on the web "how to wire" these units, and I think if a person had the inclination, it might be easy enough to wire up, and tons cheaper, however, I only solder in an emergency, so I ordered mine ready to go. Once it arrived, I put batteries in it to make sure it worked. Boy Howdy! When ON this EL wire stuff is impressive even hanging loose. Wow!
