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 2 Plus
The value choice in Abbott’s range. You give up some alarm range and the newest sensor hardware, and you keep the same fifteen-day wear for about £104 a month privately.
