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.
FreeStyle Libre 3 Plus
The most convenient of the Abbott sensors, and the longest wear time you can currently buy. If you qualify for NHS funding, get it that way — the private price is roughly £140 a month.
