Does anyone know if it can be returned or if insurance will allow you to get a different one? I thought I remembered hearing that you can't but just wondering. I'm not very happy with this CGM, especially the range. It's only 5 feet and the main thing my husband and I wanted was to put Caleb's monitor in our room overnight. Even with the low range, it keeps saying he's out of range and now after day 4 or 5 he's complaining of severe itching from the sensor. I'm over it. What should we do?
