I just wanted to say, with all of the interest in the G4, that the insertion is amazing. Coco had to use numbing cream with MM but she decided to try it without with the G4. She said it hurt less then a site insertion. Also, it has been 3 days and along with the accuracy being fabulous, and her having a high interest in how her blood sugar reacts, she has had absolutely no issues with the site. With MM, by day three, it would be itchy and by day 5 it would ooze due to her allergy to the gold filament.
