Sona Cruise stimulates the entire clitoris - even those invisible parts - with gentle sonic waves instead of conventional vibrations. This whisper-quiet sonic massager offers an entirely new orgasm, a prolonged climax after a sensual build-up. Its smooth, waterproof design is made from a single piece of premium silicone, making Sona Cruise incredible easy to clean and soft to the touch. And because Sona Cruise doesn't directly contact the clitoris, it can be used to generate multiple orgasms over and over again without any discomfort.Sona Cruise makes the unique pulsations constant during use, so when its pressed hard against the body extra power is unleashed for an intense, deep release.How does LELO's Patented Cruise Control Technology work?Specially developed by LELO and exclusive to their toys marked "Cruise" (Sona Cruise, Sona 2 Cruise and now Sila Cruise), Cruise Control reserves 20% of the full power during normal use, so that when LELO's Cruise toys are pressed hard against the body and the motor begins to drop power, that extra 20% is unleashed so that there's no reduction of intensity. It's not a setting, it's completely automatic, and it eliminates the single most common complaint against pleasure products.
