It looks like we are going to have to give up our Contour Next Link. Insurance doesn't want to pay for the strips. The doctor's office is filing an appeal, but I was told not to get my hopes up. Our choices are, Accu-Chek Avia Plus, Compact Plus, or Nano Smartview or FreeStyle Lite, Freedom Lite or Insulinx. Which is most accurate, less wasted strips (due to errors or insufficient blood fill), best for a 7 year old? Thanks!
