Cock Ring Zero Tolerance The Black Knight Vibrating Silicone

What the Black Knight is

The Black Knight is a vibrating silicone ring from Zero Tolerance: a matte black loop and teardrop-shaped pad in silicone, with a glossy ABS plastic bullet seated in a channel running across the base of the pad. The packaging lists it at 2.5 inches long, 1.66 inches wide and 0.8 inches deep, weighing half an ounce, with a single-speed motor, one-button control, and two LR-41 batteries supplied in the box. It carries a five year manufacturer warranty, and the panel states that it is phthalate and latex free, waterproof and submersible.

What defines it is how little there is to operate. One button, one speed, and a pair of watch-sized cells you can swap out — no charging routine to keep up with, and nothing to set before use. You can see the rest of the category in Cock Rings.

The two materials, and why the ring uses both

The Black Knight is made of two materials with two different jobs, and the packaging names both. The loop and the pad are silicone, described on the panel as creamy smooth; in the photographs the finish is a flat matte that absorbs the studio light rather than reflecting it, so the whole silicone body reads as a single soft black shape.

The bullet is ABS plastic — the rigid, glossy thermoplastic used for appliance housings and electronics casings. A motor and a battery stack need a hard shell around them, and the panel calls this one durable. The difference between the two materials is easy to see in the bare product photograph: the shell throws a bright highlight off each rounded end, while the silicone surrounding it stays flat and dark.

The pad is textured on one face and smooth on the other. The packaging front and the specification card both show the raised nubs, described on the panel as strategically placed; the bare product shot shows the reverse face, an unbroken smooth surface tapering to a point.

How to use it and look after it

Operation is a single button on the bullet: press to start the motor, press again to stop. There is one speed, so there is no sequence to cycle through and no setting to find again next time. That is a fair trade in the dark, and it is the whole of the control scheme.

For cleaning, the packaging gives an explicit instruction: clean with Zero Tolerance toy cleaner and a warm water rinse. Because the panel also states waterproof and submersible, the whole ring can go to the tap rather than being wiped down. Let it air dry fully afterwards — droplets sit in the nub texture and are easy to miss on a quick towel-off.

Give it a drawer, a box or a pouch of its own if you can. Silicone items stored pressed together for long periods can mark each other's surfaces, and keeping this one separate costs nothing.

Who it is for

This is an adult product for buyers 18 and over who want a powered ring without a charging routine to manage. The battery choice is the practical argument: LR-41 cells are the small round type familiar from watches and calculators, sold in inexpensive multipacks in most places that sell batteries, so a dead cell is an errand rather than a wait.

It also suits someone buying a powered ring for the first time. At 2.5 inches long and half an ounce it is a small object, the control is one button, and there is nothing to configure. If multiple speeds or a rechargeable motor are what you are after, the wider Sex Toys range covers that; this one is built around a single function.

Good to know

The packaging prints "phthalate and latex free" on the specification panel. The latex half of that statement is the one that matters most day to day, since anyone with a known latex sensitivity can rule the material out from the label rather than guessing. Phthalates are a family of plasticizers used to soften some flexible plastics, and several of them appear on California's Proposition 65 list, which is why the phrase turns up on so much adult-novelty packaging. The California Office of Environmental Health Hazard Assessment publishes the Proposition 65 warnings program and a set of chemical fact sheets if you want the general background; neither page refers to this product.

Two practical notes about the batteries. LR-41 cells are small enough to swallow, so keep both the spare pair and the used pair well away from children and pets rather than leaving them loose in a bedside drawer. And take the cells out if the ring is going to sit unused for a long stretch, since any button cell left in a device can eventually leak.

Stop using it if it causes any discomfort, and do not leave a ring of this kind in place for an extended session. The five year warranty is printed on the packaging as a heading rather than as terms, so the conditions and the claims route are worth confirming with the manufacturer before you need them.

Frequently Asked Questions

What size is the Zero Tolerance Black Knight?

The packaging lists the Black Knight as 2.5 inches long, 1.66 inches wide and 0.8 inches deep, weighing 0.5 ounce. Those are the overall figures for the complete piece including the bullet. The panel does not print an inner diameter for the loop itself, so there is no fit measurement stated anywhere on the package.

What batteries does the Black Knight take, and are they included?

It takes two LR-41 batteries, and the packaging states that they are included. LR-41 is the small round cell type familiar from watches and calculators, widely sold in multipacks, so replacements are easy to source. The panel does not describe how the bullet opens for a battery change.

Can the Black Knight be rinsed under the tap?

Yes — the specification panel states that it is waterproof and submersible, and the packaging's own care instruction is to clean it with Zero Tolerance toy cleaner and a warm water rinse. Dry it fully before storing, paying attention to the textured face where droplets sit between the nubs.

Is the Black Knight latex free?

Yes, the specification panel prints "phthalate and latex free". The loop and pad are silicone and the bullet shell is ABS plastic, both named on that same panel, and no latex component is listed anywhere on the packaging.
