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. It comes in three colors - Purple, Cerise & Black and all of them are rechargeable and 100% waterproof. SONA 2 has 12 powerful yet gentile 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. This is a massager that is easy to clean, body-safe and durable - it has up to two hours use in one go. Nevertheless, SONA 2 is an upgraded version of well known, award winning toy which makes pleasure unmistakable. Lastly, same as all LELO toys, it comes with 1-year warranty that is easy to register at lelo.com/support.
