The Nexus iSTIM is a revolutionary stimulation system to excite your erogenous zones and increase sexual pleasure to electrifying heights! The iSTIM system uses a TENS machine (Transcutaneous Electrical Nerve Stimulator) to deliver small electrical pulses into the most sensual parts of the body via electrode pads placed onto the skin or via the use of various Nexus toys. The iSTIM is supplied with electrode pads and three iSTIM attachments that clip on to the Nexus toys to make them electro compatible. These attachments can be used with the Nexus Glide, Neo, Excel, Titus and Vibro as well as the exclusive iSTIM C-Ring (sold separately) for the ultimate electrical G-Spot stimulation experience.Features: High quality electronic TENS machine with LCD displayElectro padsThree iSTIM attachmentSnap connector to attach iSTIM C-ringSafe and discreet storage caseThe Nexus iSTIM is compatible with the Nexus Glide, Nexus Neo, Nexus Titus and Nexus Vibro.
