Without making direct contact, SONA 2’s 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 hasn’t 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.
