I wanted to let you know that I received the Roller Tip and have used it right away. My first boy I used it with was in heaven! I used it on his TM joints and around the sinus points above and below his eyes. You could actually see his whole system relax. In addition, he was able to voice with me----for the first time (while I was PROMPTing him after using the Roller Tip)! Another boy said it "felt good" while rolling it on his palms and his face. I allowed him to use it as he could voice feedback for me. My first girl I use it with was very hesitant at first, but then relaxed and allowed me to use it on her TM joints. I was trying to see if it would help her reduce or cease grinding. I did feel a release on one side when I was using it on the other.
