This is a specialized product that marries two very specific types of toys - a prostate massager (only those from the Nexus range that feature a ball bearing) and a e-stim power box, such as the Nexus iStim. It is very difficult to divorce the properties of this specific product from the e-stim and prostate massage that it marries - needless to say, the enjoyment of this product assumes that a Nexus massager that is liked is in use, and also that the user likes the way that electrosex feels. This is a product for a someone who already owns an e-stim unit and a Nexus prostate massager and who knows that they enjoy both types of stimulation. Beginners to e-stim should look at the Nexus iStim instead (because it comes with these attachments included) or look into acquiring a TENS unit to play around with before picking up these attachments.

The Nexus iStim attachments are made of some sort of conductive composite - a hard plastic that conducts electricity. They fit into the ball bearing cavity on the taint massage arm of certain Nexus brand prostate massagers - namely the Glide, Neo, Titus, Excel and Vibro. I had an Excel to use with my partner, and found that the attachment fit snugly into the ball bearing cavity, and snapped around the taint arm for a close fit to the contours of the massager. When in place, the hole in the Nexus that allows for removal of the ball bearing becomes the port through which an e-stim lead wire may attach. The wire style that fits into the 'electrified Nexus' is a standard pin that is used in the world of TENS units to attach to the most common style of electrode pads. There are subtleties to getting a really good fit with a TENS wire with a pin end, but in general it will be easy to attach any e-stim unit with the correct set of wires to this accessory - the Nexus iStim will most assuredly work, as will a TENS unit procured through medical avenues (they are used in physical therapy and also for pain management; sometimes insurance covers a portion of the purchase).

Playing with e-stim requires a little bit of thinking - not much, I promise, but a little. In order to get stimulation, a circuit must be created that includes a portion of a body. Connecting to an electrified Nexus massager sets up the first part of the circuit, but an additional electrode is needed attached to the other pin on the TENS wire. This can be a sticky electrode pad, or another e-stim specific toy. Additionally, it's really fun to think outside the box and use a bit of electrical tape to tape the second pin to a metal toy like a njoy Pure Wand, turning your pure wand into the second half of your circuit. Whatever you end up doing, remember to place the pad/attachment/toy on an area that is *fun*; preferably somewhere close to the Nexus massager. If you choose well, the whole region will start to feel electrified and alive, heightening any non e-stim play that might also be happening.

Now one might think that because this attachment is for a prostate massager, that this is a very male bodied specific toy. While it is true that prostate owners will have a big added oomph when using this toy, the Nexus iStim attachment simply allows for precise positioning of a taint massaging electrode when used anally, and as a clit massaging electrode when the Nexus massager is used vaginally. It is much more precise, effective and "on target" than a pad ever gets in such restricted and often damp territory. As such, the Nexus iStim attachment (plus required Nexus massager) is highly recommended for anyone who likes e-stim and wishes to integrate targeted taint or clit stimulation into e-stim play.

TENS stimulation plays with the nerves close to the surface of your skin, but it is still a playing with an electrical circuit that involves your body. Use common sense and don't direct the circuit across your chest cavity. For a quick and dirty rule of thumb, keep it to the fun bits below the waist.
