Frequently Asked Questions

Q: Are these CGM sensor covers compatible with FreeStyle Libre 3 and Dexcom G7?

A: Yes! These WEFITON waterproof CGM patches are designed for universal compatibility, fitting FreeStyle Libre 1, 2, 3, and Pro as well as Dexcom G6 and G7, Medtronic Guardian 3, Enlite, and Abbott Lingo sensors. The precut design ensures a snug, centered fit over the sensor without covering the sensor head itself.

Q: How long do these CGM adhesive patches last?

A: Each patch is engineered to hold for up to 14 days — matching the wear cycle of most CGM sensors. The medical-grade waterproof adhesive resists water, sweat, and oils throughout the entire wear period. For best results, clean and dry the skin thoroughly before application.

Q: Will these patches irritate sensitive skin?

A: These CGM sensor covers are made from hypoallergenic, latex-free material specifically chosen to minimize skin irritation. The flexible, breathable fabric allows airflow under the patch, reducing the likelihood of redness or discomfort even during extended wear.

Q: Do these patches interfere with my CGM sensor readings?

A: No. The patches feature a no-center-glue design — meaning the adhesive only contacts the skin around the sensor, not the sensor dome itself. This ensures your glucose readings remain accurate and the sensor can be cleanly removed at the end of its cycle.
