    We started on the t:slim X2 in May of this year, moving from our Animas Vibe. This ofcourse brought the change to Dexcom G5 (from G4).

    Our experience with G5 has been the most frustrating experience in a while. We found G4 to be very reliable, but with G5, we often see a dreaded "48T" alert that indicates sensor errors. Once we see the 48T, the sensor is unlikely to recover. And it happens on a new sensor too (anywhere from a few hours to a few days old).

    Replacing the transmitter didn't help, and moving the sensor to different body areas didn't help.

    Has anyone else seen this 48T alert? I'm lead to believe it's fairly rare, yet we seem to be see it every couple weeks or so. And this alert isn't documented in any user manual as far as I can tell.
