Should last longer on your body
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
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.

Works perfectly
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 as good as advertised
The tape does not stay on for a week like the sensor does. Have to put another type of tape over it. Will not buy again

Will stick
I have been able to wear it for a week. Waterproof, which is great. And so far it hasn’t caused me to itch, I’m very sensitive to the glue that some companies use.

Clear coverage
I really like this product. I’ve been using the flesh colored sim patch on my CGM but even though I can clearly see my CGM with this patch it’s much nicer on my skin and appearance.

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

They seem better than the ones provided by Medtronic, when I get my supplies. Will definitely but again as a just in case purchase

I have found these patches just right. They are large enough and have sufficient adherence to provide secure fixation of the sensor. They are relatively easy to apply even on the triceps area (posterior upper arm) . They are available at a reasonable price and unobtrusive

My wife uses the Medtronic Guardian 4 CGM sensors, but has had problems with water leaking under the adhesive patches that come with them when showering. She had been using Tegaderm branded patches, which cover the entire sensor, but even these are not completely waterproof, so seeing these patches we thought we would give them a try. From the description it appeared as if these were going to be larger than the Tegaderm patches, but they are, in fact, slightly smaller. The patches themselves are also very fiddly to apply, due to the paper covers causing the patch to pull and twist, causing it to stick to itself, and once that happens there's no going back and the patch has to be thrown away. I fit her sensors and apply covering patches, so I'm used to dealing with these kinds of things, but I found the application extremely fiddly and problematic. After a few tries we got one covering the sensor, and my wife tried it in the shower, however water still leaked through under the surface of the patch. She has had to resort to wrapping her upper arm in clingfilm to try and keep the moisture out. Upon trying another patch, she wore it during a particularly hot day, and found that it eventually worked loose due to sweat accumulating under the surface.
