I use a Dexcom7 CGM. I have been consistently using a sensor for at least 14 days. There has been only one time that i needed to change a sensor before 7 days. I have been using the current sensor for 28 days! My meter #'s are consistent with my CGM #'s.
What is the record for longest use? If you live in my area, Kirkland, WA, I'll buy you a Starbucks if you have gone longer than 28 days.
