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.
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.
