The second in the new Black Collection is the Black Collection Medium. It is just that little bigger, offering that bit more of a stretch and a fuller feeling. This rounded and curvy BiPolar electrode is based on our popular Bobble electrode but that bit bigger to satisfy those wanting that bit more.

You will need

Low Profile Cable A cable with
4mm connectors
4mm Cable

Designed for Pleasure

Like the majority of our Premium Electrodes the contact points are top and bottom rather than side to side, providing a more natural feeling action when the electrode moves and is suitable for both vaginal and anal stimulation.

Quality at every level

Featuring our luxurious Satin finish this smooth dual sphere, double waisted design means you have options. Insert it as far as the black insulator and feel the sensation focused at the opening or insert the second sphere and those tingles will be that bit deeper delivering the pleasure to uncharted areas.

Produced to our usual high standards using aircraft grade materials all of The Black Collection will, if cared for, last for years.

Every electrode is fitted with heavy duty 4mm sockets in the base. If you are considering longer term use, then we suggest using our Low Profile Cable as this is more comfortable and will allow for it to be either worn under underwear or sat on by the user without the fear of breaking a connector.

Lifetime guarantee

As with all of our Premium Electrodes The Black Collection are covered by our unique Lifetime Guarantee. They are all supplied in a custom-made Smokey Black re-usable protective storage tube.

Easy to Clean

Cleaning is simple and easy. Any one of The Black Collection can be disassembled and immersed and washed off in hot water with light detergent and then wiped dry. Caustic cleaning substances are not a good idea as this may damage your electrode, and obviously you need to make sure the electrode is completely dry before storage.

I bought the Black Medium a while ago on recommendation from JS' online review. The insertable part is intense and filling, blinkin' brilliant. The electrode touches all the right places for me. E-Stim's machined finish is flawless and obviously without sharp edges. Use lots of water-based lube or conductive gel. Great to explore e-stim!

All I can say is WOW, this is a fantastic electrode and its size and weight is terrific. I prefer using it full inserted but if you only insert the first ball you get very intense feelings around the entrance to whatever orifice it has been inserted into. I love the feeling of being ghost fucked and while I couldn't take this one anally my friend loved doing so and it was so much fun watching her trying to get it in. Top Tip use lots of electrolube as it helps a lot with big electrodes.


Additonal Options:


You will need a cable to connect your electrode to your control unit.
Non E-Stim Systems control units may require a TENS style connection, but may not have the power to drive
the larger electrodes.

Conductive Gel

We always recommend our Electro conductive Gel for use with insertables.
Manufactured to give a smoother more comfortable response, and suitable for internal use, it is far superior over other more 'sex toy' orientated lubricants.

Disinfectant Wipes

Pack of 12 sterile disinfectant wipes
