5. Screaming O
The Screaming O is the product, which started the whole Screaming O product line. Since it was first released to the market, it has remained one of the best selling vibrating rings in the world. With a beaded ring, and raised dots on the stimulator, it provides more pleasure spots for both partners, compared to the entry level product of most brands. Even as a disposable vibrating ring, it has a long battery life of 40 to 45 minutes. The material is made of food-grade silicone with no phtalate nor latex, and is very stretchable and comfortable to wear. It was voted by Women’s Health Magazine as the best “Top Product” and “Best Ring” for 2007. The European Erotic Trade Organization also awarded it the 2009 “Innovator of the Year”.
