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

OK, so I have purchased these multiple times, to use as overpatches for my Tandem TruSteel insertion sets. The FIRST batch worked AWESOME. The SECOND batch worked well, with a small amount of lifting around the edges. The THIRD batch peels up horribly all around the edges, 1/4 to 1/2 inch of lifting. Note that I use very a aggressive skin prep routine, so it's NOT a skin oils problem. Also note that I switch them out every 2-1/2 to 3 days, so it's NOT a long term use problem. (These are marketed as CGM overpatches, so they SHOULD work for 10-14 days, right?) Conclusion: Diminished quality means I am going to have to look for a BETTER alternative. Sad really, since the potential to be a GREAT product was obviously there, based on the performance of the initial purchase.

These have worked great in protecting the Freestyle Libre from snagging the sensor and protecting it from moisture. Come off fairly easily so long as you shave the application area. Just shave, clean with an alcohol wipe (all standard practice for the sensor) and apply. Having someone assist with the application makes it much easier; these are thin, and the adhesive is aggressive, so having someone else apply is much cleaner. There are two sides, adhesive and outer; the cover is 3-piece for the adhesive so you can locate over the sensor, then uncover the side strips to complete adhesion. The "blue" guide band on the outer 2-piece cover makes it very easy to align with the sensor.

This adhesive cover takes a couple practices and wasted bandages before you master applying it without it doubling over or crinkling on itself. The adhesive covers will come loose around the edges almost as soon as it’s applied. With fair wear and tear, after 8-10 days the cover is barely hanging in there. It does cover your FreeStyle Libre through showers, so that’s a positive. When taking it off though, the adhesive leaves a thin dark circle of sticky fibers from abrasion with your clothes. That residual circle takes adhesive remover to get it off your skin!

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.

I was using a similar product with adhesive over the entire application side. When I needed to replace the patch before my sensor, they would stick so firmly to my sensor that it was extremely difficult to remove without also removing my sensor. This product however, does not stick since they have eliminated the adhesive from the sensor area. The sensor is covered, but uncompromised. I can typically wear one for about 10 days before the edges start to roll and I need to replace the patch. Not sure why they don't last the full 14 days, but I can't complain. The adhesive does not leave residue on my skin nor does it cause a rash like other products have in the past. Wearing the patch gives me a comforting sense of security knowing that I will not inadvertently bump and knock my sensor off. They also helps maintain the integrity of the sensors adhesion. I will absolutely be ordering these patches again and will continue to do so as long as I use my current BG monitoring system. This is a great product with extended wearability for a reasonable price. I would definitely recommend them.

Numerous Sensor Covers did not Stick to the Skin. They instead started Curling Up and fell off.

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.

I bought these after using the ones that are like bandaid fabric. These cover a larger area and are so easy to apply. They stick so well. They are inexpensive for the amount (48). I highly recommend for anyone with a sensor that need coverage. My husband uses the Libre 3 but they will cover different types of sensors.
