Power Ultra Ring 7-Function Vibrating Silicone Cock Ring Mack Tuff

What the Power Ultra Ring is

The Mack Tuff Power Ultra Ring is a vibrating silicone ring for adults, supplied as a single unit on a blister card. The card prints three specifications: seven functions, 100% silicone, and a weighted metal ball. Everything on this page is taken from that printed wording and from the bare product photographed beside the card.

It is catalogued with the store's cock rings and also sits among the vibrators, because it pairs a wearable ring with a motor rather than being a purely passive band.

How the ring is shaped

The ring is a single black moulding with three distinct parts, and the shape is unusual enough to be worth describing properly. The opening at the centre is splined rather than smooth: a ring of rounded internal teeth runs all the way around the bore, so the inner surface is a repeating pattern of ridges and channels instead of one flat band. Above the opening sits a broad moulded housing that spans the full width of the ring and carries the motor. Below the opening, the body widens into a short tapering apron and then narrows again into a slim stem that finishes in a small rounded ball. The card names that component the weighted metal ball, so the ball at the tip carries a metal core beneath its silicone skin.

Two practical things follow from that geometry. The splined bore spreads its hold across a series of separate contact points with open channels between them, rather than pressing as one continuous band of the same diameter would. And because the ball sits at the end of a flexible stem rather than being fixed against the ring, it hangs and swings on its own — its mass is what you notice from it, independently of the motor running above.

About the silicone

Silicone is a synthetic polymer built on a backbone of silicon and oxygen rather than the carbon chains that make up most plastics, and that backbone is why it behaves the way it does in a product like this one. It is mixed and poured while still liquid, then moulded and set into its finished elastic form, which is how a ring, a housing and a stem can exist as one continuous piece with no glued seam, no threaded collar and no bonded joint anywhere along it. There is nothing on this ring that can work loose, because there is nothing assembled from separate pieces in the first place.

Finished silicone is also non-porous, so the surface does not absorb fluids and can be washed clean rather than only wiped down. The one piece of care knowledge that catches most people out is counter-intuitive: a silicone-based lubricant can gradually soften and degrade a silicone surface, because the lubricant and the device are chemically related. Use a water-based lubricant with this ring. If you want to be certain about a product you already own, put a small amount on the underside of the apron, leave it briefly and check that the surface has not gone tacky or swollen before using it properly.

The seven settings

The card states seven functions, controlled from the housing at the top of the ring. Step through the settings in order to find the one you want rather than hunting for a specific pattern, and refer to the printed insert supplied in the pack for the control's position, the battery type and the procedure for replacing cells. Fit and position the ring first and change settings afterwards — the housing is easier to reach when the ring is already seated than when you are trying to do both at once.

Fitting, cleaning and storage

Stretch the ring evenly with two or more fingers when putting it on, rather than pulling it open from one side, which is what tears a silicone ring over its service life. The housing is designed to sit uppermost and the weighted stem to hang below; rotating the ring changes which surface each part rests against without altering how the bore fits, so it is worth trying both orientations before deciding you dislike one of them.

Wash the ring before and after every use in warm water with a mild unscented soap. Two places hold residue on this particular shape: the channels between the splines inside the bore, and the narrow neck where the stem meets the ball. Work a soft cloth or a soft brush into both. Because there is a motor in the upper housing and a metal core in the ball, this is not a device you can sterilise by brute force — no boiling, no dishwasher, no long soak in a basin. Rinse it briefly, dry it completely, and give it time to air before putting it away.

Store it on its own in a cloth bag or a dedicated box. Soft materials left pressed against each other for months can mark, and a black silicone surface will pick up colour transfer from dyed fabric, soft PVC or finished leather if it is stored in contact with them.

Who it suits

This is a reasonable pick for an adult who wants a ring with the motor already integrated instead of a plain band plus a separate bullet that has to be held in a pocket or a loop. The one-piece moulding means there is no clip to lose and no pocket seam to clean out, and the splined bore and hanging weight give it a different character from a smooth, flat ring.

It is the wrong pick for three people, and it is more useful to say so plainly. If you want something with nothing electrical in it at all, a passive silicone ring will outlive this one, because the life of any powered device is set by its weakest electrical part. If you dislike added weight or find anything pendulous distracting, the ball is part of the moulding itself and cannot be detached. And if you need an exact internal measurement before buying, check the insert in the pack or measure a ring you already wear comfortably — ring sizing is personal, and a figure that suits one person is wrong for the next.

Good to know

A snug-fitting ring should be removed immediately if you notice numbness, tingling, coolness, a change in skin colour, or any discomfort that does not settle as soon as the ring is off. Do not wear one while asleep or while under the influence of alcohol, and do not wear one over broken or irritated skin. Anyone with a circulatory condition, a bleeding disorder, reduced sensation, or who takes medication affecting circulation or clotting should speak to a licensed healthcare professional before using a product of this type. Keep it out of reach of children, and keep the packaging and any small components away from children and pets.

Inspect the ring before each use. Run it through your fingers and look along the inside of the bore and around the neck of the stem for splits, nicks, soft or swollen patches, or any area that no longer springs back to shape. A silicone ring that has started to go soft in one spot is at the end of its service life and should be replaced rather than stretched one more time.

Frequently Asked Questions

How many vibration settings does the Power Ultra Ring have?

Seven. The card prints "7 Functions", and they are selected from the moulded housing that sits across the top of the ring.

What is this ring made of?

The card states 100% silicone for the ring itself, and separately names a weighted metal ball as a component of the lower stem. The silicone is a single continuous moulding — ring, upper housing, apron and stem are all one piece, with no bonded joint between them.

What is the ball on the bottom for?

It is a weight, named as a weighted metal ball on the packaging, carried at the end of a short flexible stem below the ring. Because the stem flexes, the ball hangs and moves rather than sitting rigid against the body.

Which lubricant should I use with it?

Use a water-based lubricant. Silicone-based lubricants are chemically related to the device itself and can soften a silicone surface over repeated use; oil-based products are also best avoided, since they resist rinsing and leave a film in the splines.

How will my order be packaged?

Orders are sent in plain outer packaging with no product imagery, brand wording or category description printed on the outside. The sender line on the label is non-descriptive, and the contents are not itemised anywhere on the exterior.
