G7 Adhesive Patches Waterproof 20Pack G7 Overpatch Flexible CGM Tape Non-Glue Central Full Cover Hypoallergenic & Latex-Free Stelo Patch Overlay for 10-15 Days Long Stay, Multi-Colored

They were good for my Dexcom sensor, especially in the pool. I found a couple clinkers that didn’t work very good but other than that they’re pretty good and I actually got to swim so that’s a plus because I love to swim.

Purchased as a replacement to an out-of-stock similar product of a higher price and quality. In my experience, these stayed on about the same duration as my CGM sensor is advertised to last. In some cases, it peeled off sooner than expected, but the adhesive on these makes it easier to remove than the brand I replaced. Inexpensive, these are worth the price for an easy-to-remove patch which works well enough.

It was exactly what I needed: a patch that fully covered the sensor and not just the tape around it. It blocks things from catching on it, which is the issue I was having with my g7 sensors. They would get stuck on something, and peel away from the adhesive, making the sensor stop working. The patches would be great IF they stuck on well. They last about 5 days for me if I'm lucky. I've tried them with and without skintac applied under them and it doesn't seem to make a difference either way. I've had to use at least 2 per sensor session every time since I bought these, and yes I am using rubbing alcohol to clean the area before applying the sensor and the patch. I would buy these again if they stuck better but I'll be looking to try another brand after I run out, if I can find others that don't have an open hole in the middle.

The instructions are worthless.Before installing the sensor, to exfoliate the skin under the sensor and to ensure adhesion good enough for frequent lap swimming, I wash and scrub my skin with a washcloth, soap, and water.If you have sensitive skin, use a technique that works for you.I use lava soap. It might be relegated to the automotive department or order it with this order.I also include a scrub with 2% peroxide on a paper towel. Peroxide kills only those bacteria that contain catalase enzyme (the enzyme converts peroxide to oxygen gas and pops the bacterium), but it may help remove more dead skin.Then wet a paper towel with rubbing alcohol and scrub. Let it dry. 70% kills bacteria better than 90% but either works. With the loose dead skin removed, the sensor and patch will not come off until you want it to.After it expires, if I have trouble removing it, I sometimes use "goo (be)gone" water based adhesive dissolver, which I believe is harmless. This is not the similarly named "goof off," which is not safe for skin contact and probably wouldn't work anyway.Install the sensor in a place under your upper arm that both avoids muscle and lets you see it. If you can't see it, get someone to help. Alternate arms. If you haven't removed the old sensor, mark it with a sharpie.To achieve a smooth application of the patch, fold the patch in half across the two small edge papers. Remove one of the larger pieces leaving the exposed adhesive away from your skin. Place the unglued center cloth over the sensor and slide it around until no adhesive is going to touch the sensor. Then unroll the exposed side onto your skin. Next, partly remove the other large paper and fold so you'll be able to pull it out. Remove one side paper and smooth it down. Remove the last two papers in a way that works for you. It helps to fold tabs you can grab.Note that the sensor doesn't have to be kept dry except to keep it attached. Also, it doesn't need access to air. The hole in the top of the sensor is used during application for the needle that guides the thin sensor wire through skin. The holes around the side allow water to drain out, but with this waterproof patch, they aren't needed.

If you have a stelo or dexcom, get this one. It’s better than the one that comes with the glucose monitor. A bit of residue from glue when you remove it but that’s expected

Patches are extremely sticky.

These do not stick like advertised. So far I’ve only been able to get it to stay completely stuck for about 3 days before I have to replace it. I’ve gone through many patches. Thankfully I only have gestational diabetes so I was never going to need the whole pack anyway, but still it’s rather frustrating to keep having to replace the sticker every so many days. I’ve read the instructions thoroughly so I know I am doing the procedure correctly. But alas, it never fails the sides start to roll up after a few days and showers. If I needed these long term I definitely would seek out a different brand.

I like them. Keeps my CGM from catching on clothes or other things. Only weird thing is, the lighter colors last the 10 days, but the dark ones always have to be replaced. It's a small thing and worth it to me.
