LELO Sona Cruise is a unique clitoris stimulator. The vibrator uses sound waves to stimulate the clitoris and the sensitive parts around it. Sona Cruise has a soft, round opening which sucks in the clitoris when you place it on your vagina. The blood will be drawn upwards, which makes the clitoris more sensitive. Then the sound waves provide an intense pinpoint stimulation. Thanks to LELO Cruise Control, you will still feel the stimulation when you push the toy against your body. LELO Sona Cruise has 8 settings that can be controlled with the push buttons on the handle. Sona Cruise is rechargeable and is 100% waterproof.
