Colarr80 Pcs Waterproof Sensor Covers Compatible with Libre 2 and 80 Sensor Stickers Set Transparent Adhesive Patches(Star)

Hole is too large to cover FreeStyle Libre 3 sticky part that comes out from the sensor. It is easy for someone else to put on the back of the arm. It can easily be peeled off or comes off just wearing it. It's too light weight. Can't be waterproof if it doesn't cover sensor tape. I don't imagine it would be waterproof even if it DID cover the sensor with a smaller hole. Material is just not strong enough.The person that reviewed about cheap crinkly plastic did not remover the top portion of the cover. It's really thin. Thinner than plastic wrap. Thinner than the stuff they use in America to cover IV site for security. Won't hold up for a day much less two weeks. I used two in one day and gave up on them as they don't fit over the sensors tape or stay on. Not even band aid strong.The nice flower sticker on top of the sensor is also to big and over laps the sensor. It does not make up the difference of the clear cover for the two to make a proper seal. There is still a gap between sticker and plastic cover.Looks nice on the ad but doesn't work. Needs better quality control to fix issues.Picture of three. Only the flower shape cover fits correctly for Libre 3Blue stripe paper/plastic on cover.White portion taken off to see cover.Both sides taken off cover to show how thin cover is.My fingers in picture showing both paper and plastic off but still one blue strip on.Crumbled up sensor cover still with one side attached.Picture with them stacked on top of each other you can tell the flower shaped cover is the size you need.Flower shape cover to show sizes, full dismission and center hole size.Picture showing flower shape cover and over lap from one of the flower stickers.I would show pictures of the covers on but no-one wants to see Grandma skin on the back of her arm. lol

Wasn’t the right size I needed so I returned them. The credit was extremely fast too!

Please save yourself the trouble and don’t buy these. They don’t fit and they don’t stick very well not worth the money. I bought them and had to return them because the quality was terrible. The design is very cool but the overall performance was very poor. The sticky clear part doesn’t stick not waterproof at all and doesn’t do as described.

stickers dont cover enough area so that the clear cover fits.

These "sensor covers" are nothing more than paper stickers. The first one used lasted less than 24 hours. NOT waterproof. The clear over lays are not solid, they have a hole in the middle and are supposed to fit over the sensor. They are huge, much larger than the sensor itself. Complete waste of money.I can use them for sealing envelopes.

These are good little stickers, as long as you realize what you’re getting and can use them the way we use them. I probably read it wrong, but for some reason I thought I was getting a sticker that would cover the entire sensor, then be big enough to be the entire large circle we are all used to seeing. However, what this sticker actually covers is the center part that just goes over the sensor itself. The reason this is actually super helpful though, is that this sticker goes in the center and has just enough overhang, that when you place one of the more typical stickers on the market, that just goes around the sensor and leaves the center free, over this sticker, the two stickers together protect the sensor fully even better than the stickers that are just one whole complete sticker. My daughter is a teen and also loves being able to mix and match patterns between these and the stickers that go around. Let’s face it, the stickers that just go around almost do the job, but not really, and adding these cute overhanging center stickers is such a great solution

These do not stick properly. Wasted several before one worked. Too much of a pain so threw them in the trash

i don't like that the cover is just a smidge too small for the sensor, it is not quite free on all sides. it is a pain in the butt to apply solo given where the sensor is meant to be used and it doesn't create a tight seal if any part of the cover is touched during application. i won't be purchasing this again.

The cover are too small for the ring to attached

I must've ordered the wrong one but I ordered for my Libre Freedtyle 2 and it did not fit. The stickers around and ontop did not fit but they look cute.

Comes separate and don't stick together or fit properly

I did not like this product because they came separated and they are hard to put on. The outer circle patch does not go on smoothly as shown and the stickers don't sit nicely over top. Not impressed.

I went swimming. The stuck to my censor and it got wet and lifted.
