PPMAK-Sensor Covers for Libre 3-50 PCS Adhesive Patches-Waterproof CGM Tape Long Lasting 14 Days (for Libre 3, 50 PCS)

I usually use a full water proof cover with no center adhesive for my Libre3. However in the hot weather, and any swimming the Libre3 doesn't function well when completely covered. It needs to "breathe". There is a reason that the hole in the top of the sensor is relatively bigger than the one in the 14 day and Libre 2. These precuts with no hole in the center help extend the edge adhesion of the Libre 3 sensor and protect the cloth rim that extends from beneath the actual sensor. These tapes are smaller and very light. Can't even feel them there. If you need protection form the sensor being bumped off these are not wide enough to place a reusable bump cover on. I have sensitive skin and have had no reaction to these at all. They are easy to put on and remove, but adhere well and keep my Libre3 in place the full 14 days. I saw other reviews that complained that they were not "water proof" because they do provide coverage in the center over the sensor. The tapes themselves are waterproof. They are meant to protect the cloth edge around the sensor from water and lifting, and they do exactly that. If you repeatedly jam your sensor only a reusable bump Gaurd type cover with a full cover over it will help prevent loss from that problem. But as stated, these extend and protect the adhesive edge of the sensor, and prevent water and other substances from causing the sensor adhesive to give out, and they still allow for skin healthy evaporation of sweat and water that get into the sensor and thus preserve healthy skin and sensor function. I will be buying again.

good

The first time I purchased this item I was pleased with it. It didn't always last the full 2 weeks, but long enough to make it worthwhile for me to order it again when I was running out. At that time I would have given it 4 stars.Unfortunately, the product changed between my two purchases, and not for the better.First, the adhesive is different. It does not stick. I haven't had one last for more than an hour and when I remove it, my skin is reddened where the adhesive did stick. I did not have this problem the first time I ordered these.Second, the material itself is different. It is not as "giving" for movement, so even when it did stick, I could never get it on smoothly and I could feel it pulling on my skin when I moved my arm.I will NOT be buying this item again.

Product does an excellent jog. Keeps cgm dry while showering and protects it too. Like the metal package they come in, keep them organized and protective, much better than a cardboard box, Arrived next day with Amazon Prime.

This did cover my sensor but noticed irritation after it started to lift, then by the 3rd time I used it was worst reaction. It blistered and swelled. Went Urgent care, it was an allergic reaction. I do not react to adhesive on Freestyle sensor but this cover has something in it that causes my skin irritation and allergic reaction. I like the security of it being an extra layer but I can not use anymore. Be careful and use with caution. Everyone is different.

They don’t exactly stay on for 14 days but longer than the other brand I purchased. As long as I’m not sweating they are wonderful and they have saved me from knocking the sensor off. Before I was replacing the sensors often and my insurance didn’t cover them so they were expensive.

didn't stay on after showering

So I just got my sensor, and I was afraid of it falling off . But I found these and they worked perfectly. They last for two weeks and honestly, it’s hard to get them off which I love it gives me the protection that I want.
