Hey all -
I’ve had the Dexcom 7 for about 3 weeks. Since then I have had 5 bad sensors, the receiver had a scratch screen when I got it (not a big deal until) I started getting dust under the top layer of the screen. There has been maybe 3 days where the Dexcom is accurate within 5-10 pts or even 20% of my meter. When that happens I absolutely love this device.
However, after my first 3 sensors failed yes, they sent me new ones, my 4th sensor lasted about a day of great readings until it stopped showing the arrow after going down 30-60 pts in 2 or 3 readings, showed me going up 300 when I was at 140, show me steady at 90 when I was in my 50’s etc.
I have tried doing the calibrations once every 15 minutes 3 times to see if that helps which it does for about an hour. I am just seeing if I am having bad luck or I’m doing something wrong.
Any tips appreciated
