I know the transmitter on my Dexcom G4 is out of warranty after 6 months, and I've had mine for 8, with no problems yet. I called my insurance company to see how much it would be for a new one (I figured it would be better to have one around as a backup) and I was told it was $1,600, $1,140 with my insurer's negotiated price.
That's a lot of money. I decided it was better for me financially to just wait until the transmitter (NOT the sensor) dies and then replace. How long have other people's transmitters lasted?
NOT sensors. Transmitters. Thank you!
