LELO LUNA Smart Bead
The LELO LUNA Smart Bead is a vibrating Kegel exerciser that fits inside the vagina and acts as a personal trainer. The Smart Bead follows a five-minute workout in which the user squeezes the PC muscles when the Smart Bead vibrates. The toy also rates users' orgasm potential based on muscle strength. Smart Bead is made of body-safe silicone and is fully waterproof. It is powered by a single AAA battery.
