Declining adhesive quality
Color: Blue
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.

Work Great with Freestyle Libre Sensors
Color: Blue
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.

Don’t Waste Your Money
Color: Green
If I could give zero stars, I would. Within minutes the adhesive starts to fail. Continuous Glucose Monitors are pricey, and you want to make sure they have the best chance of lasting two weeks. This product is oversized and not durable. After three applications, each lasted less than one day. I ended up getting a different product that costs 3x more and it’s doing a fabulous job with one application. Stays put, no wrinkles, completely waterproof.

They roll up after adhering
Color: Green
They stick, but paper is tough to get off. They also begin to roll up from clothing , bed linens, etc, I end up cutting it off. Not sure if they aren't big enough or should be smaller.

Happy with these sensor covers
Color: Green
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 apply/replace
Color: Pink
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.
