ANSV - since your prior post started out Ouch, Ouch, I thought it was a good time to mention Zingo. One of your prior posts stated that a friend described the injection as a punch in the arm. I contacted their IR and they described it more like a puff of air. Wouldn't you be surprised for a device approved for a 3 yr old to produce any pain? I'm invested because of "Adlea", but I thought you would be interested in the companies description for Zingo.
