It's rechargeable and 100% waterproof with a wide mouth for better reach. Without making direct contact, SONA 2s sonic waves offer fast yet gentle clitoral stimulation for mind-blowing pleasure. Compared to original bestseller, SONA 2 has softer, deeper and overall bigger mouth for complete satisfaction - both inside and out. Medical grade silicone hasnt changed, but upgraded so that's extra soft to the touch. SONA 2 has 12 powerful yet gentle enough settings so every user can find the perfect pace. The second change, which came for more convenient use, is the way SONA 2 turns off. Instead of pushing and holding (-) on the control board, the middle button () acts as setting changer and off button.
