Well, I like it and I would purchase again. I like techie toys and it is cool to get info on my iPhone. The connections are a little buggy, but for the most part it works. Most notable is what it doesnt do. Doesnt control the pump, which I didnt expect but would be awesome. Doesnt display all the info: last bolus and amount, last hard reading, it has the info but cant be accessed in app. (Weird thing, the Carelink mobile site intended for sharing data with others actually displays more info, including alarms, just not the personal app) You cant put in notes, which would have kicked it up to four stars at least and doesnt seem like a difficult thing technically or regulatory wise. That would improve the usefulness of Carelink tremendously. Biggest disappointment: doesnt alarm. They missed the opportunity to fix the inadequate pump alarm. THAT would give it five stars and would be a genuine advancement in management AND safety! First iteration, so hopefully improvements will come. Maybe even a link to a nutrition and exercise app. Yeah, those seem important items for interpreting insulin and glucose data. Seems you would want them in Carelink. Out of the gate, it really adds little to management, just cool tech and a more seamless upload. like cool tech so that is well enough, but I hope they can add substance down the road.
