Nuanchu 48 Pack Sensor Covers Compatible with Freestyle Libre 1/2/3,Waterproof CGM Sensor Patches, Glucose Monitor Protector Long Lasting Without Hole (Blue)

I was looking for a waterproof sensor/charger cover that would last a full week on my CGM. Even though this is marketed for Freestyle Libre 2/3/4, I decided to give them a try. They fit perfectly well on my Guardian 4 sensor/charger. I change the sensor every seven days and, so far, these sensor covers have made it the full time. Granted, there may be little areas around the periphery that begin to peel up, but nothing major. If I were wearing a short sleeve where that would show, I'd simply replace the patch. Normally my site is covered because I don't like to advertise that I'm wearing it.The full coverage provided along with the non-stick center circle make me really happy. No sticky mess gets onto my sensor charger. It's very easy to peel-and-stick the patch on, then remove the outer cover by grasping along the "ruffle" in the middle and peeling away those two outer portions. Voila! Ready to go for another week.I do recommend these. For me, having the "ruffled" pull-away part after the patch is on makes removal of that paper part much easier for me than when it is just a straight cut.

Easy to use and easy to take off.

These are horrible! I've tried to make them work, but every time, they start falling off within minutes. They curl up on the edges and don't really help the sensor to stay in. I even put them over the sticker that comes with the sensors. They just aren't sticky enough. The image I uploaded is the patch I put on 30 minutes ago (over the sensor patch that was falling off, too).

The first one fell off within a day. Then I cleaned the skin with a 70% isopropanol swab, and it has been on for a while. No peeling! So, for me at least, the instructions are an issue. I also have no idea what the difference is among the colors and why the difference in price between them.

Works well for it's purpose better when you have help putting them on.

easy application but started peeling around the edges after a few hours. center is a cloth material not sticky which is nice but the peeling is disappointing. would not buy again.

excellent

Super happy with these! I’m not a dainty girl, but didn’t realize how often I run into doorways or scrape the crap out of my arm in the washing machine. These have saved countless monitors from being ripped out. I feel stupid for waiting until I lost three of them!
