I think all of us here prefer the "real thing" I know I do but sometimes when the real thing isn't available a quickie with a vibrator is of good use. It also helps in the bedroom with a couple. personally I have used them for many many years and never once have I had one that shocked me. although one time I did have an electric one short out and I threw it across the room and then to the trash lol soon bought a new one lol
