SIMPATCH Universal Adhesive Patch, No Hole (25-Pack) (Black)

Has great adhesive and works amazingly to protect my husbands sensors.

My CGM usually adheres well for the entire time I wear it, but occasionally, it loosens up, so I'll apply one of these and there is no way it's coming loose.

It tends to wrinkle when applied. I fixed it by cutting slits in the patch. Fits much better now.

After using the Libre for a year, I was frustrated that even with SkinTak, My Libre would be barely hanging on with three days left. Then, I read an article from an Endocrinologist who HIGHLY recommended the SIMPATCH. So, I Ordered the SimPatch for Libre (https://www.amazon.com/dp/B078H3CWZ9/ref=cm_sw_em_r_mt_dp_M453BN6GKPDZ2ZDBC6AF) , which holds on to the thin adhesive edges around the Libre (you can read my review here (https://www.amazon.com/review/R2B0KWCNLZWPDL/ref=cm_cr_srp_d_rdp_perm?ie=UTF8&ASIN=B078H3CWZ9). My issues were very similar to others, so I Thought I would give this one a try, as it fully covers the sensor with about another inch extending past it.THE GOOD:* It holds up. - I've used these with 2 sensors so far - the first sensor, I was swimming frequently, and the patch lasted about 7 days. This current sensor, I have only swam three times and it made it the full 14 days.* Easy to remove - The adhesive is strong, but not so strong it tears up your skin or you pull the Libre off with it. IMO, its a fine balance and they got it. If the adhesive was stronger, would it last 14 days with swimming? Sure. But I'm willing to bet it would be a much more uncomfortable process to remove. For me, I'm good if it lasts 7 days.THE BAD:* It is a flat circle. Looking at the images, I thought it would have an outdent for the sensor - this is not the case. So, you have to be a little more careful to try and center the patch and ensure it has a decent seal around the sensor, so water does not get in (even during a shower) and work away at the adhesive of the patch and the sensor.While not a perfect product, it does solve the problem I had, so I will continue to purchase these and would recommend.

I love these, I was having a lot of trouble with the monitors coming off or getting caught on clothing, etc.These do the trick! They do leave some adhesive residue but a good scrubbing will remove that. Worth the money not having to replace the monitor after a day or two.

Good quality even though it might be a little overpriced. No allergic reaction or rash or anything.

I tried this brand for my insulin pump pod and those work great. Strong adhesive for the 3 days for the pod. Thought they'd be good for the libre sensor button too since the adhesive seemed more solid. The first 2 times I used them for libre, they stayed on my arm for almost the full 2 weeks of the sensor life, The next one was ok for about 4 days and peeled up and it was tricky to pull it off the sensor without pulling the sensor off my arm.. you know this is being done with one hand right? I was hoping these patches would have the non-adhesive center so if you have to change the patch, it isn't fully glued to the sensor.This last time I used one, it started to peel up after 4-5 days, but it wasn't too bad yet. Last night the peeled part that wouldn't stick to my arm anymore, apparently was sticky enough to attach to my pajama sleeve and when I rolled over the entire patch and sensor pulled off my arm, stuck to the pj-sleeve.Simpatch, you need to make a version of these that has the adhesive free center, so if the patch peels off on it's own, or has to be changed early, it doesn't take the sensor off with it. stickiness to skin is a totally different animal than stickiness to the sensor, or fabric/clothing... skin sheds off, so it's easier for the patch to peel off the skin on it's own, but solid stuff like the sensor or one's sleeves.. or bedsheets, blankets... it sticks more firmly to these things. Having adhesive in the center of the patch is a rea problem. I understand that the adhesive on Simpatch is heat activated.. so if one sleeps on the side the sensor is on.. body heat between your arm and the bed, trapped will make any peeled edges of the patch stick firmly to any fabric it contacts... and make the bond on the sensor even stronger... which means... it will pop off when you roll over or touch your arm. If they make a version with fabric in the center that is non-adhesive over the button I'll consider buying them again.

I have tried several methods of securing the freestyle libre to last the full 14 days and have had the best success with the round Simpatch with no hole. I change it at 7 days and it is never even loose around the edges at that point (not the same for some of the others I have tried). I could probably get the full 14 days out of it but I start getting nervous when I see the edges getting loose which happens after 10 or 12 days so I just got in the habit of changing weekly. Been trying to figure out a way to have it not stick so well to the sensor itself to make that mid sensor use change a bit easier but so far I have not had it pull off a sensor when changing so not a big deal. The libre does not have enough tape outside the area of the patch for me to get the Simpatch with the hole in the middle to be effective for me.Great product, delivers quickly and has never let me down.Thanks
