What does a warming cock ring do? A warming ring has a small heating element inside the silicone. On the Rumbler, the ring heats up to a maximum of 122°F and takes about 15 minutes to get there. The idea is comfort and sensation: a warm ring feels closer to body temperature against the skin than cold silicone, and the heat adds to the vibration. Switch it on ahead of time if you want it warm from the start. The vibration works separately, with 3 speeds and 7 patterns.
Rumbler: a cock ring that rumbles and heats up
The Rumbler from Jock is a vibrating cock ring with a built-in heating function. It delivers rumbling vibration in 3 speeds and 7 patterns, and the ring warms to 122°F in about 15 minutes. It is made of silky, body-safe silicone with plastic parts. The inner diameter is 1.8 inches, the overall diameter is 3.3 inches and the ring is 0.7 inches thick.
A remote changes the settings from up to 26 feet away, so you do not need to reach down with lubricated fingers. The ring is rated IPX6 waterproof, which means it can go in the shower but must not be submerged. It recharges with the USB cable provided.
Best for: For men and couples who want more than a plain ring. The vibration can be shared with a partner during sex, and the remote lets either person take control. It also works for solo use. The thick 0.7 inch band and 1.8 inch opening suit average to larger sizes.

How to use
Charge the ring with the USB cable and fit one AAA battery in the remote. If you want heat from the start, turn the warming on about 15 minutes before use. Apply a little water-based lubricant to the inside of the ring and put it on while you are soft or semi-erect, sliding it to the base of the shaft. Use the remote to choose a speed or pattern. As general guidance, wear a cock ring for no more than about 20 to 30 minutes at a time. Take it off right away if it hurts, feels numb or feels too hot.
Care
- Use only water-based lubricant on the silicone.
- Wash the ring with warm water and mild soap after use. Do not submerge, boil or machine wash it.
- Dry it fully, especially around the charging point, before recharging with the USB cable.
- Keep the remote dry and remove its AAA battery if you will not use it for a while.
- Let the ring cool, then store it away from other silicone toys.

Frequently asked questions
Will the 1.8 inch ring fit me?
The inner diameter is 1.8 inches and the band is 0.7 inches thick. The distributor does not state how far the ring stretches. A 1.8 inch opening is on the roomy side, so it tends to suit average to thicker shafts.
How hot does it get?
The ring warms to a maximum of 122°F and takes about 15 minutes to reach it. That is noticeably warm against the skin. If it feels too hot for you at any point, remove the ring and let it cool down.
Do I need batteries?
The ring itself is rechargeable through the USB cable provided. The remote control runs on one AAA battery, which is not included, so have one ready. The remote works at a distance of up to 26 feet.
Can I wear it in the shower or bath?
In the shower, yes. It is rated IPX6 waterproof and the distributor says it can be taken in the shower. It should not be submerged, so do not wear it in a bath, pool or hot tub.
How long can I wear it?
The facts give no time limit for this ring. The general advice for any cock ring is about 20 to 30 minutes at a time. Take it off sooner if you notice pain, numbness or discoloration.
