### ⭐⭐⭐⭐⭐ Sensor overlays

### ⭐⭐⭐⭐⭐ Should last longer on your body
*by S***Y on January 24, 2026*

Work well just wish they stayed on my arm longer. They start pealing up around day 6 and my CGM is good for 15 days. So I have to use two per device, that is a wast.

### ⭐ ALLERGIC REACTION AND PEELED
*by E***A on November 14, 2025*

Made my husband’s arm break out in a rash. It was also very itchy. It did not hold up for even one day, but immediately started to peel up around the edges, exposing the sensor to water and the elements. This was also extremely difficult and convoluted to apply. I don’t recommend purchasing.
