Weird looking, I admit. But so good. I had no idea what sonic waves could do and my surprise was really big. Sometimes I press the toy against my body, sometimes I keep it at a very short distance. The toy pumps out sonic waves and they go deep into the tissue. It is hard to describe that sensation. So strong and so good that sometimes I drop Sona. My body keeps reacting even without the toy. I had never had such an experience. It is not even power but the way the pulse hits. Incredible.
