The ‘plus’ is more accurate than the previous models. Many people who have used both MM and Dexcom have found Dexcom to be “better” – but some have also found the opposite, and Abbott Navigator seems to have a lot of very satisfied ex-Dex users.
My point was that none of them can compete with fingerstick meters for accuracy. When the Rep says that the “Plus” is better than the previous “Seven”, I strongly agree, but that’s not the comparison which I was making.
Restarting a Sensor: Yes, when the 7-day timer expires, you just do the “Start Sensor” without touching either the Sensor or the attached Transmitter. After the 2-hour “warm-up” delay, you get at least a few more days. I can nearly always get an entire second period, but I’ve made a habit of quitting on day 13, while the old one is still almost certain to be performing well. (I no longer wait for it to actually “go bad” and give poor readings before I tear it out.)
You can always use “Stop Sensor”, at the bottom of the menu, to do your Restart before 7 days has passed. That way, you can schedule the 2-hour waiting period to occur at a safe, bG-stable, and convenient time.
