"Share more" with the Mio from JeJoue. Throw away (or better yet, recycle) all of those $10 vibrating rings you've picked up from the drug store and try the Mio on. Powerful vibrations, coupled with pulse patterns make this toy a cut above. It is also waterproof, rechargeable, and is made of comfortable and durable medical-grade silicone.
This toy comes with JeJoue's 1-year warranty.
