Warning: current must never flow through the heart. Do not use if you have a pacemaker&#44; are pregnant&#44; if you suffer from epilepsy&#44; or on any broken or inflamed skin.<br /><br />The high quality laminated construction of our probes means the electrodes are built in to the main body of the probe. This means the conductive surfaces will never become detached or wear out! You can also use this bi-polar probe as a uni-polar probe by just connecting one cable instead of two. Stimulation will only be felt on one side but by adding a smear of conductive gel across the base will effectively create a fairly good uni-polar probe. <br /><br />You will need an ElectraStim erotic electro stimulator to use this item. If you are using a different power box and your cable does not have the 2mm pin connector you will need an adapter kit. Exclusive design.&nbsp; Crafted from an engineered laminate of marine grade aluminium and acrylic. 56mm penetration depth by 30mm diameter. O-rings around the base form a good insulating grip and can be removed for effective cleaning. Rotate the plug to vary the sensations. 2mm pin socket compatible We take a piece of 3mm thick clear acrylic&#44; bond it between two solid metal bars with aircraft strength adhesive&#44; add 2 nitrile insulating o-rings&#44; press a 2mm pin socket into each pole&#44; then shape and polish Mini electro plug to a fine finish. The result is spectacular. <br /><br /> *Lubricants are a natural up-sell to electro stim toys as they are needed to completed the circuit between the toy and skin&#44; and also help avoid skin irritation. Water based lubricants are recommended based on their high ability to conduct electricity. Silicone is a natural resistor and is not recommended.<br /><br /> <div>Please note: this item requires a powerbox to function.</div>
