Worn over a penis owning partner's shaft (or shaft and balls) or over the base of a favourite dildo, this 100% silicone cock ring provides some seriously effective erection enhancement benefits plus perfectly placed vibration. Position the vibrating section up top in the path of a mate's clitoris or perineum, or flip it around to target the wearer's balls. It's nice and stretchy for easy placement but holds reliably tight to prevent slips and ensure a rock-hard erection (if that's what you're into!).

The Round has 10 settings and is waterproof. Changing them is done by clicking through with the button on the side of the vibe. Conveniently rechargeable via USB with a magnetic charger. It'll run for up to 40 straight minutes on a full 1-hour charge. There is a 1-year warranty. 

The Round stretches from approximately 1" (2.5 cm) in inner diameter
