Mystim Cluster Buster, wireless eStim device starterkit

The Mystim Cluster Buster is a wireless e-stim device: a handheld digital controller that sends programs to small receivers, which plug into your Mystim electro toys. With no cable running from controller to toy, the person holding the controls can be across the room, and one controller can run several toys on different channels at once. This starter kit gives you the controller, one Sultry Subs receiver and a self-adhesive electrode, so you can begin straight away and add more later.

How the wireless system works

Each Sultry Subs receiver clips onto a Mystim toy and is set to a channel from one to eight. The Cluster Buster talks to those receivers wirelessly, and each channel's intensity can be adjusted on its own. Mystim says any number of receivers can be controlled at the same time, so you can link several toys to the same channel or give every toy its own. That's what makes it different from wired boxes, where every toy needs its own cable back to the unit.

Programs, intensity and the Shock button

The controller has 12 stimulation programs, plus five additional programs, and 10 intensity levels per channel. The output is an asymmetrical biphasic square pulse, at frequencies from 5 to 70 Hz and pulse widths from 30 to 260 µs, shown on a backlit display with lit buttons so it's readable in a dark room. A dedicated Shock function lets the controller deliver a sudden burst on demand, which is popular in power-exchange play. Agree on how and when it's used before you start.

Starting safely with an e-stim device

Electro play is safe when it stays below the waist. Never place electrodes on or across the chest, near the heart or on the head and neck. Don't use e-stim if you have a pacemaker or other implanted device, a heart condition or epilepsy, or if you're pregnant, and keep it off broken or irritated skin. Always start at the lowest intensity, raise it gradually, and turn it down before moving or removing an electrode. Use a water-based conductive gel on contact points for even sensation; the starter kit doesn't include gel.

Building your set-up

The included bipolar adhesive electrode is enough to get a feel for the programs. From there, you can add Mystim toys such as the Magic Gloves or an electro cock cage, and extra receivers like the Sultry Subs Channel 2 to run more than one toy.

Charging and care

Both the controller and the receivers have built-in lithium-ion batteries and charge by USB, with a cable in the kit. Charge everything before a session so a receiver doesn't drop out mid-play. Wipe the controller and receivers with a barely damp cloth; they aren't meant to be rinsed. Clean toys and reusable contacts according to their own instructions, and store the whole set in the included case.
