To use this
egg-shaped vibrator for female, you simply need to unscrew the battery compartment (located on the bottom of the toy) and insert two AA batteries. Then pop it back into place. The first time you use this egg can be a little tricky since there is no on/off switch. Instead, when you first turn it on, press and hold down either button until its vibrations come alive. To turn off your egg, just press and hold down that same button until all lights have gone out.
