Life Savers
This is my second order of these and they are well worth the money. My husband has been using a Libre 2 for monitoring his blood sugar. He was always worried about them falling off before the two weeks of use was up because he'd catch it as he walked past door frames, or it would get loose after showering. He couldn't go swimming for very long with our daughter. I bought these and it's just changed the game. Occasionally he'll replace the sticker before the two weeks is up, if he's been swimming and it peels up a bit, but generally it's one sticker per libra wear. totally water proof. Sticks well. Peels off without much effort, and only a little tender. Really recommend.

Great for added protection of Libra 2 sensors.
So glad I found this product! I was constantly knocking my Libra 2 sensors off until I found these! Because they have to be applied to the back of your arm, I need help to get the patch on but that’s just because of the location, they are easy to apply. I tend to clean my skin with an alcohol wipe before applying and they stick and last for 2 weeks. The pink and blue line is irrelevant as that’s the top layer you peel off so you won’t see that when on your skin. The only down side, which is to be expected, you do get a slight dark gummy line around the edge when you take them off but a bit of nail varnish remover gets it off no problem! Great product, great value as they do last and very glad I found them!

Ideal for libra
These work really well and stops the dislodging of the Libra disc. The pink stripe is purely where the separation of the top cover is so they are completely clear when put on. A little fiddly to get off all the 2nd layer but once you get the hang of it it’s fine. No had any problems, waterproof and best of all no more worrying about the disc catching on anything

Secure and comfortable
I have used these for 2 sensors only so far but each time have needed only 1 patch each. They are a little fiddly to apply but, even as a complete newbie, I managed it on my own. Both patches have stayed firmly in place for the 2 week life of the sensor despite (not very sweaty) excerise and daily showers. They were easy to remove with very little adhesive residue too. Most impressed.

They’re ok
Purchased these for my daughter as a 2nd layer of protection for her libre 2 sensor, they’re pretty hot and miss adhesive wise, some have stuck really well and stayed in place where as others have peeled off within 24 hours. I probably will purchase again, when they’re good they really do work well

Adhesive stickers for covering sensors for Diabetes control
These are so good i fact I would go as far saying they are amazing for the freestyle libre 2 sensors I was having problems with them coming off, these have solved the problem they were recommended to me by the Diabetes team . I would fully recommend them to anyone who uses this system Thank you .

Waste of time and effort
When I came across these I thought that they would help by adding that extra layer of protection for the sensor, however this was not the case. When I first applied the initial patch it all seemed great and almost invisible, as the day went on the patch started to lift and by the evening I had to remove it as it was only stuck to my sensor. I thought I was doing something wrong or even had something on my skin that made the patch lift. So then next morning I cleaned the residue off from the previous patch and made sure that the area around my sensor was clean and dry then applied another patch. Fast forward afew hours and it's lost all adhesion to my skin and almost pulled my sensor off when I removed my top. They are a good idea in theory but they need to be improved for practical applications.

Cover peels off - Adhesive fault?
I should have heeded the other reviews that highlighted these do not stick well. I bought the pink variant and it peels off after a couple of days. These are the worst version of this type of cover that I have purchased.

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.
