Can you imagine what life was like before batteries and sex toys? We don't even like to imagine! Sure, there were probably some primitive dildos and such, but everyone had to get off (gulp!) manually! Fortunately for us, we live in a time of whisper quiet, discreet, battery-powered sex devices, like the Micro Tingler, that get us off in an instant. Requires 2 AA size batteries, not included. This oversized vibrating bullet provides great clitoral, vaginal and anal stimulation at the touch of a button! Thank goodness for technology!
