"..Afraid of being electracuted." that's the only reason?...*grin* 2AA batteries wont hurt you....go for it!
(This brings back memories-24 years ago, I worked in an adult book/toy store for awhile--some of the products we sold are still available! I guess they are the right thing for some people!)(The 'remote control' I remember was just a cord...not a wireless....the user was expected to choose her OWN time and place.....which seems much more sensible. If cell phones are dangerous, imagine BZZZZZ in heavy traffic!)
