I previously bought a cheap meter from the 'zon and it was junk, giving me readings that were impossible based on the A1C values I was getting from the doctor. I did my research and settled on the Contour Next One and it is amazing. Bluetooth connection to my phone so that I have an easy to access history in the app, and I can connect multiple meters (work and home) and get a combined history. I love the color coded display and lights, really easy to understand at a glance and peace of mind when it comes up green! And most importantly, the readings on both of my meters are well within the expected ranges and seem to be accurate (ate a few too many cookies the other day and my numbers shot way up). I've only been using them for a brief time period so far, but I have no reservations about them at all; they've been easy to use and accurate. Shipping was also fast, which I appreciate for medical items! And I had a minor issue with my order that DW immediately fixed, so good customer service too! (and to be clear, I haven't been paid or anything for this review, just a very happy customer!)
