What does the accuracy figure mean?
MARD is the average gap between what the sensor says and what a laboratory blood test says, as a percentage. A 10% MARD means readings are off by about 10% on average — so a true 7.0 mmol/L might show as anywhere around 6.3 to 7.7. Lower is better. Most current sensors sit under 10%; twenty years ago they were over 20%. No sensor is exact, which is why treatment decisions still get confirmed with a fingerstick when a reading does not match how you feel.

What works well
- No prescription needed, and the plan does not auto-renew
- Minute-by-minute readings, more granular than most consumer sensors
- Thirty-day money-back guarantee on a first purchase
What to watch out for
- The advertised price is an introductory offer, so budget for more than that on repeat purchases
- No glucose alarms — it is a wellness device, not a medical one
- No published peer-reviewed accuracy study
Our verdict
A reasonable way to spend two weeks learning how your own meals move your glucose. Treat the headline price as introductory, and do not rely on it if you manage diabetes with insulin.
