Dexcom G6
Superseded. Choose it only if a pump or clinic you depend on still requires it — otherwise the G7 is more accurate and warms up far faster.
Dexcom ONE+
Dexcom’s value sensor, and the cheapest route to alarms we have found. Worth comparing on yearly cost rather than sensor price, because ten-day wear closes most of the gap to the fifteen-day Abbott sensors.
