Q: How long does one patch last?
A: Each shield is designed to last a full sensor wear period. Wear time varies with skin type, activity and climate.
Q: Can I swim and shower with it?
A: Yes. Sensor Shields are water- and sweat-resistant. Press the edges down again after swimming for the best hold.
Q: Using a different CGM?

These new slightly elongated patches give me more coverage on my sensor.
They stay on and can be worn in water.
Hi Judith, we're so glad to hear that you're happy with the patches! Thanks for sharing your experience.
They work great. Stick to my skin for 2 weeks just fine. Sometimes it starts to pull up on a small section. I just cut those off as close as possible and push down on the rest, and it doesn't come up anymore.
