I received this item and it does not work. I think the battery is dead because it does not vibrate. I don't even know where to get a battery for it. It shouldn't arrive to me with a dead battery. It also looks cheap and to be blunt, I don't know too many men that this cock ring will fit on unless they have a seriously small penis. I'm not gonna torture my man by asking him to try it on. I'm just disappointed with the whole thing. Maybe it's meant as a novelty item rather than as a sexual thing? save your money.
