Plug the Intruder Extreme Electro Butt Plug into an ElectraStim stimulator and you'll enjoy intensified stimulation across a wide surface area. The cool metal enlivens with electrical signals that cause your body to tingle, contract and pulsate in time with the selected pattern setting. Intruder is the smallest of our extreme range of metal butt plugs but is still recommended for experienced players. Please note that in order to experience the full power of larger metal electrodes you will need to use our AXIS, Flux or SensaVox stimulators.
