What happened to the good ones?
I use these no holes to cover my Medtronic Guardian sensor 4. The tape that comes with them requires2 as the rules me they didn’t stick well. If I showered with in 6 hours of a new one, it would come off in 12 hours. I have been buying these for 3 years. My last order of the exact same seemed all well til I purchased a new order in Jan 2025 but I didn’t start using them until last month. They are not the same as I previously got 2 other times. They feel the same One thing I have noticed and I see it in the review photos is when the adhesive side is not stuck and looks milky white. IF while placing this on and then going to remove the paper from the sticky side, the patch lifts up or you try and nudge it a bit, even a 1/4 inch, the part that was on and you moved, gives NO second chances. B4 putting it on, I fold back the blue scalloped edges so it removes from the middle out to the edges easily. Again if the edge stuck and got moved when you peel the paper off, it’s as good as XYZV! And will either need to be replaced then or add another on top of the milky edge.Butnthere’s a big problem, these new ones do not stick well at all. First Q rolled off on day 3, next one 4 days and I added extra tape on top but it didn’t stick. The last one had been on for 3 days but the edges were lifting. I went out to do yard work in the NH heat and half was no longer stuck on. This was placed on the side of my thigh and covered but my shorts. This never happened with this product before so I don’t know what has c Hagen but I will purchase these again nor will I be recommending them to other uses.

Works well to hold sensor in place.
They work on any CGM sensor, which is a plus to help keep in place while showering or in everyday use. They apply easily and hold up well. They stay in place and no sliding out of position. The package has 50 covers so no problem about running out. They are a good product to have around if your sensor is easily pulled out of the arm while moving around.

Surprising incredible adhesive strength super light weight transparent adhesive covering bandage!
Wow -- overall excellent value and helps protect your Freestyle Libre 2!. Keeps your sensor device in place so you can actually get continuous glucose monitoring! Waterproof -- yes, very much so unless the edges get rubbed for whatever reason and avoid underwater if any edges have curled up from working out, rolling in sleep, bumping it, scratching at it inadvertently. If the seal around the edges is perfectly applied you could get a half hour bath. Stays after ten minute showers. Transparent -- yes, very much so! Adhesive very strong so avoid hairy areas. If you're expecting a single order to last the year, that may not be the case. We have to switch out adhesive bandages sometimes twice a day definitely twice a week. Not quite sure what to use to help remove the leftover stickiness because skin underneath get a little red from the adhesive glue. Overall happy, --this was the second solution we tried to keep being active while keeping a continuous monitoring system in place to evaluate glucose. Able to continue showers and baths as usual. Instructions are a little hard to read the font size. Maybe add a link in the product listing to instructions? There was one issue that was a little bothersome - product wise: the package was not factory sealed and the number count of adhesive coverings were off by about 10% from than the advertised quantity. Tried to get this issue taken care of via website and the item can't be returned and there's no way to get the missing quantity replaced . Tried to mention this to customer service through the online website and was not able to get it remedied. The usefulness of the product really outweighs the incorrect count you may receive. And while the individual adhesive bandages have a protective plastic on both sides of the bandage the outside seal of the package comes opened and the count was off. But the thing is that kind of keeps you wondering was it used before and returned? Because of the plastic backing on both sides of the adhesive bandage there's really no easy way to remove a backing and reapply it perfectly back to a factory state. With the COVID pandemic you kind of want items you purchase for your health factory sealed you know? And some sort of easy method to facilitate removal without creating redness or raw skin irritation. . Active folk may have to keep reapplying new adhesive bandages approx every 36 hours onto the same sticky areas while gently holding the sensor (cause it's a tender area from the micro needle) so the sensor doesn't get pulled off when you remove the adhesive bandage. The CGM sensor manufacturer should really supply a pack of these coverings with each sensor or at least provide some to evaluate so you can avoid having to wait for replacement sensors when they fall out or prematurely fail do to lack of having a protective adhesive covering bandage like this product. Sensors are doomed to fail prematurely without a covering and this one overall does the job.

It doesn't last 14 days, but still a good product to have to save the CGM.
These don't last close to 14 days. The longest we've gotten is maybe 5 days before the edges loosen and get gross and annoying. The rest of the patch sticks really well; it's a bit painful to peel off every 5 days and if it weren't for the edges I think it could stay on 14 days. I just think it needs to go back to the design boards. Even carefully putting it on, you can tell that some edges have no adhesion to begin with. That being said, my son will still always wear these because we didn't have luck with his CGM staying attached to his arm as long as they should and I would rather be replacing a sticker every couple of days than replacing/wasting an expensive CGM.

Mine turned black over time
I had no issues with them; they worked exactly as they were supposed to. No trouble putting them on, and they stayed in place just fine. The only thing I found strange was that they started out clear but gradually turned black over the 14 days. When I replaced the sensor and cover, the entire thing had turned black, not just the edges—even the part covering the sensor itself. At first, I thought it might be dirt, but the patch was still firmly in place when I removed it, so dirt couldn’t have gotten underneath. After taking it off, the cover itself appeared to have turned black. I always swab my arm and the area where I’m placing the sensor and patch with alcohol beforehand to ensure a clean start.

Arm perfect for diabetic device cover
Worked great to protect my device.

These work and are of a decent price compared to local pharmacies.
Decent product. There are additional plastic covers that must be removed on the top, too. I put my first set on, and it didn't mold to my arm very well and was stiff. I didn't understand that there was a stiff plastic outer layer (a fine slit on the blue stripe). If I buy more of these kinds of shields, I would likely just get an opaque cover, maybe with some fun pattern. The plastic is translucent, but it makes your skin look wrinkly. Saying that, most of us who need a CGM are old, so we are already wrinkly. Thus ends my whining. These work and are of a decent price compared to local pharmacies.

Justo lo necesario, muy buena compra. Tenía miedo de que fueran de mala calidad pero no, pegan bien, no me causaron alergia y duran perfectamente los 14 días.

Such a very clever solution to keeping the 14 day life cycle of this product, and its cost is well and truly recovered by maintaining the useful period of these expensive units. I found then whilst looking through Amazon and have not seen this product advertised here in Australia. It should be.

It's painful to see the pricy sensor falling at first day, then suffer with the bad costumer service Abbott Ireland has to get a solution or replacement. This is a life saver, avoiding the hassle from the start, attaching to skin seamlessly.

I use the Libre2 sensor system for my blood sugar information. Great system, but the adhesive on the sensors isn't that good, and sometimes a slight bump causes the sensor to become dislodged - and useless. These sensors cost almost $100 CAD every 2 weeks. Enter these GREAT sensor covers!! These cost $12 CAD for 36 covers = 18 months. They work extremely well! Easy to attach. Well manufactured (in a resealable air-tight pouch) and absolutely no quality issues. They cover the Libre2 sensor with a non-adhesive center, plus an additional 1.5" radius of cellophane-like adhesive that's 100% waterproof, and will not peel off until you do so to replace your Libre2 after 14 days. Easy to remove, but still adheres to your skin. BEST: they leave no adhesive residue on your skin, and no marks or other issues with skin reactions, etc. The signal from the sensor is not impaired or degraded in any way. Not often do you find products that are BETTER THAN ADVERTISED, but these covers certainly are. I'd buy them again - and in fact already have.

I have tried patches from everywhere, none lasted like these. I take 2 showers a day and go to the gym 6 days a week and these patches easily last the full 2 weeks. 100% worth the money and do a great job at stopping you knocking sensors off and keeping them on for the 2 weeks. Also recommend getting some adhesive remover wipes for when you are done.
