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.

Medtronic Simplera

The sensor to look at if you use or want a MiniMed 780G pump, because that integration is the reason it exists. As a standalone sensor the seven-day wear and two-hour warm-up make it hard to recommend over the alternatives.
