Beisar Launches Prometheus E-Stim Chastity Cage
A new cage from Beisar pairs lockable chastity with remote-controlled electrical stimulation. Here is what the launch actually offers — and the safety rules that come before any of it.
Adult pleasure products manufacturer Beisar has added a new device to its chastity range. Announced on 26 October 2026, the Prometheus is a remote-controlled electrical stimulation chastity cage, built to combine adjustable restraint with customisable e-stim. It follows the company's earlier PTERO chastity products and sits alongside its existing e-stim devices, Thor and Perun.
The device itself is a 2.95-inch PVC cage supplied with three interchangeable rings, adjustable restraint straps and a traditional lock-and-key mechanism. The stimulation system is aimed at the glans and offers three electrical pulse patterns with six intensity settings, all controlled through an included wireless remote — so a keyholder can adjust sensation from across the room, or from much further away. The package includes a rechargeable stimulation unit, a connection cable, the remote, the rings and the locking accessories.
One practical detail stands out: Prometheus has a front urination opening, a feature Beisar added after customers raised the issue with its earlier PTERO products. It is a small thing, and it is exactly the kind of thing that matters when a device is meant to be worn for hours rather than minutes.
What this launch says about the market
Chastity devices used to be simple: a cage, a ring, a lock. The Prometheus shows where the category is heading — restraint plus sensation, controlled remotely, with the keyholder in charge of both. That combination is powerful, and it is also the reason the safety conversation has to come first.
Electrical stimulation is advanced play, not a beginner's toy. It should only ever be done with equipment designed for the body, used exactly as the manufacturer instructs, and only between consenting adults who have agreed the limits in advance. Never improvise with household electronics, never use e-stim above the waist or near the heart, and stop immediately if anything hurts. A device that adds sensation to denial does not change the basic rules: fit it properly, keep it clean, agree an emergency release, and check in with each other.
Key point: a new device does not make a new dynamic. The cage is a tool; the structure, the rules and the trust between keyholder and wearer are what make chastity work.
For anyone curious about chastity but not ready for a device with stimulation built in, the honest advice stays the same: start simple, learn your fit, and add complexity only when the basics feel easy. A first cage should teach you about comfort and hygiene before it teaches you anything else.
