A green led light does come on when you hit the caps lock button. I threw it on the floor while plugged in and jumped on it rolled it up and threw it against the wall and it works great, supposed to be easy to wash and water proof, but i don't think ill throw it in the washing machine, plus its just portable. Could be a good weapon if you wanna smother your old lady or choke her to death. Might be great for spankings, still have lots more r/d togo...
