    I hate checking in public. With the libre I can just pull the reader out of my purse and scan my arm for my blood sugar. This helps me catch lows.

    I have had to get used to wearing it on the back of my arm. I need Skin Tac and Sim Patches to keep it on for 2 weeks. I knocked the first 3 sensors off before they expired. Abbott replaced them all for free. Now I have a routine that works and I am getting the full use of each sensor.

    Checking with the Libre is fast and easy.
