LiangMai 20 Pack for Medtronic Sensor Patches，Waterproof Guardian 4 Sensor Cover Patch，Easy to Use Pre-Cut CGM Sensor Patches Protect Your Sensors Continuously for 7 Days Long Stay

Fantastic product only one out of all the products that sticks on my skin, very durable under water and in the heat, very effective, has a good stickiness to it, great value for money

This product works well

Works perfectly for coverage over the Guardian 4 sensor. Found easiest to place properly over sensor when patient is lying down on bed where arm can be relaxed. Less risk of gaps/bubbles in the patch that way.

Not good just fell off

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.
