Dexcom G7
The sensor to pick if you want alarms, remote following, or pump integration. The gap between its pivotal accuracy figure and the independent one is the widest of any sensor we list, and worth knowing about.
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.
