The Small Slider carries the one-inch head used on the Flange, and the Large Slider uses the 1.5-inch head from the Moaner. Both keep those familiar heads but add an adjustable neck.

The neck slides through the base and locks at any length with a small hex key. Three neck lengths cover the range: Long at 75mm, Standard at 55mm, and Short at 35mm, all sliding from a 3mm minimum upwards.

Loosen the lock screw with the supplied key, slide the neck to the desired length, then tighten the screw back a quarter-turn. Test it with hand pressure before use.

Sliding into the Slider

The Slider range actually started life as an idea a few years ago. Someone asked the question we'd been turning over in the workshop for a while - Why are insertable electrodes always one fixed length? You buy a Flange, you get the Flange's neck. You buy a Moaner, you get the Moaner's neck. If you wanted a different gap between the two contact points, you bought a different electrode. That's it.

It's not how anything else works. You wouldn't buy a separate camera body for every focal length. (I might, but then I am mad and into cameras.) The honest answer is that fixing the neck is the only sensible way to make a range work. We could offer the Flange in five neck lengths, the Moaner in five neck lengths, the Bobble in five neck lengths - but here's the catch. Whatever sizes we picked, we would have guaranteed the size *you* want isn't one of them. And the logistics of keeping every size of every electrode in stock would be a nightmare. So everyone settles for "close enough," and that's how insertables have always been.

Customers would ask if we could make a longer neck. Or a shorter one. Or one that was a specific length for them. Technically we could create various neck sizes, but we would also have to create the bolts, and then maintain stock across multiple ranges. It was just not realistic. But the idea of letting customers pick their own neck length stuck around and we kept it on the list. The result was, The Slider.

As you can see, we wanted to do something different with the Slider. One electrode, one head you've already chosen, and a neck that moves to wherever you want it.

But what is it?

The Small Slider carries the one-inch head our Flange customers will recognise straight away. The Large Slider steps the head up to an inch and a half, picking up where the Moaner left off. The same heads people have loved for years. But with new trick up the sleeve.

Is it Magic?

The trick is the neck. It slides through the base of the electrode and locks at any length you want with a small hex key on the side. Three neck lengths cover the full range - Long at 75mm, Standard at 55mm, Short at 35mm - and all of them slide from a 3mm minimum upwards. The Standard ships fitted. The Long and Short are extras you can swap in when your play asks for it.

Like virtually all of our insertables, you can take the Slider apart for cleaning. Head, neck, base washer, body, locking screw - five pieces, every component, every time.

How it feels different

If you're coming from a Flange or a Moaner, the head shape will be familiar. The Slider lands in your hand the same way. What changes is what happens after that.

A fixed-neck electrode has one feel. The contact points sit where they sit, and the sensation that produces is the sensation you get. The Slider gives you a dial on that. Bring the head and base closer together and the current path through the body shortens — the sensation tightens up, sharpens, gets more concentrated. Open it up and the same intensity setting feels broader, more spread, a longer sweep through the tissue. Same Slider, same powerbox, same gel. Different play.

It's texture, not just intensity. The dial on the powerbox controls how strong; the neck position controls *what kind of strong*. Two parameters, not one. That's the Slider's job.

How to set it

Set the neck length with the Slider in your hand, before you go anywhere else. Loosen the small lock screw with the supplied key. Slide the neck where you want it. Tighten the screw back, again a quarter-turn. The locking screw has a nylon pad on the end that grips the neck without scoring it, so firm contact is what locks it, not force. Test it with hand pressure before you start. That's the routine.

You can even adjust mid-session if you want to. It is easier to adjust the electrode when it is out of the body, but it's there if you want it.

Choosing the right neck

Both the Sliders ship with the Standard sized neck giving you 55mm max neck length.

The Long Neck at 75mm max is for when you want full extension - more depth, more scope, more of a stretch in how the electrode sits. If you've found yourself wishing the Standard went further, then the long neck is the answer. If this sticks out too much at the back, then consider the Short Neck.

The Short is for sit-down comfort. If your anatomy doesn't want the full reach, or if you've worn an insertable for an evening and felt the base getting in the way of just sitting on the sofa, the Short Neck is the one to consider. with less 'stick-out', less interference, it is easier to wear for longer.

Between them, you can tune the electrode to your own body. Which is the whole point.
