The handling is simple and logical, without the magnifying glass to read instructions: battery or battery (AA) in, stick and switch contact gel pads. A small green LED that flashes every few seconds, displays operational readiness. A red (not infrared) LED lights between the pads on the skin. Whether an effect, I can not judge. (Measured about 36V AC voltage pulses) at level 1 on the dial it tingles noticeable on the skin; the higher levels go turning the dial towards Elektrisiergerät holding all about 5s per "tripping". A nice gag. With significant snoring noises unfortunately nothing has been triggered (perhaps the wrong pitch?), Even when passing strips on the ceiling not (thankfully!), But if you is so that you exhale on Mic, you have to expect Kribbel attacks. At level 1 the wakes you gently, you rotate and so it should work well too - if it was because respond to snoring sounds. In short, the idea is nice, but the function not fully developed!
