Hanna has been on her dexcom since mid November. Love doesn't cover it. She changed today, the last sensor went for 20 days! It got a little wonky this am, yesterday at day 19 was about 15pts off her bg, for the first 18 days was never more the 10pts off. Still can't believe it lasted so long, so accurately. That was her 3rd sensor, the 2nd one gave her a rash, so she was more careful placing this one, making sure she cleaned the site well. She has a little rash, but really minor. It has caught lows, but more for her, highs that she can treat rather then ignore. It's such a game changer.
