Description
The Rock Army Kingcobra harness dildo has a double-density liquid silicone dildo, a suction-cup base and can be used with a harness. It measures 24 cm in total length and 4.77 cm in diameter. The straps are made from PU leather and nylon, with metal details; you’ll also find 3 silicone rings in different sizes in the box.
Who it suits and who it doesn't
You can use it vaginally or anally, and the suction cup lets you attach it to smooth surfaces or walls. The material is described as hypoallergenic and odourless.
It may not be the usual choice for your first anal toy: at 4.77 cm in diameter, you’d generally be better off starting with something narrower.
How to use it and look after it
- To use it with a harness, fit the dildo into it.
- If you’d rather use the suction cup, attach it to a smooth surface or a wall.
To clean it, use a little soap and warm water. Then spray it with a sex toy cleaner, such as Waterfeel Toycleaner.
- It can be submerged in water.
- Wash it before and after each use with warm water and mild soap or a toy cleaner.
Compatibility
- Lubricant: As a general rule for silicone toys, use water-based lubricant: silicone-based lubricant can damage the surface.
- Water: It’s waterproof and has IPX7 protection, so you can use it in the shower or bath.
General tips
Common good practice for this type of product; these are not the manufacturer's instructions.
- The anus doesn't lubricate itself: use plenty of lube and add more as soon as you feel any friction.
- Start slowly with your body relaxed, breathing deeply as you insert it. If you feel pain, stop: anal play should never be forced.
- Given its diameter, it isn't the best choice as a first anal toy: the usual approach is to start with a narrower one and work up in size gradually.
- Don't move it from the anus to the vagina without washing it first, or change the condom covering it.
- The suction cup grips best on smooth, clean, dry surfaces such as tiles or glass; on rough or porous surfaces it won't hold well.
- Keep it clean and dry, away from heat and sunlight, in a fabric pouch or its box and apart from other toys: some materials react when they touch and become stained or misshapen.
- If you share it, wash it between one person and the next, or cover it with a new condom for each person.
How it differs
- Rock Army Tiger Dual Density: The Kingcobra measures 24 cm in total length and 4.77 cm in diameter, while the Rock Army Tiger Dual Density measures 14 cm and 4.46 cm: choose the Kingcobra if you’re looking for a larger size, or the Tiger if you’d prefer something shorter and narrower.
- Rock Army Tiger Dual Density: The Kingcobra dildo is made from liquid silicone, while the Rock Army Tiger Dual Density dildo is made from TPE: choose whichever of these two materials you’re looking for.
Our verdict
The suction cup and the option to use it with a harness give you two ways to position it; before choosing it, pay particular attention to its 4.77 cm diameter.
Before first use, read the manufacturer's instructions that come with the product: they are the reference for its use, cleaning and safety.
