An essential purchase for anyone with diabetes, hypoglycemia, or with sugar sensitivity to accurately record and monitor blood glucose levels. The CodeFree unit is a nice small size (95cm x 45cm x 15cm), simple to use and accurate. Comes with easy to understand instructions, self-test diary, test strips (you’ll run out fast so consider buying extras) and a CR2032 battery. Lower cost than Accu-Chek and better than the AC model I had previously. I like simple, so the CodeFree works for me. Recommended.
