Yoga is a soft, super stretchy, silicone erection ring with an imbedded throbby, rechargeable vibrator. Two different rings to choose from (in terms of snugness), and two different surfaces to deliver the vibration to someone else during penetration. The vibrator is easily removed for cleaning but we don't suggest getting the vibrator itself wet. Easy plug-in recharger means that you will not run out of power in the way that can happen with those tiny-tiny watch batteries.
A nice rechargeable ER worth exploring!
