Adhesive Patches for MEDTRONIC Guardian and Other Sensor, Waterproof & Sweatproof CGM Patches, Long Last Sensor Patches 15 PCS, Beige

It has great adhesive. It lasted 7 days over the life of the sensor.

These sensor patches are the best! It fits perfectly over my Guardian 4 sensor. And leaves NO residue - none on my transmitter and none on my arm! It is breathable and leaves my skin with no irritation (and I typically have such sensitivity to anything). I don't use any of the tape the Guardian comes with. I just insert the sensor, plug in the transmitter, put the little tape tab from the sensor over the transmitter, and then slap on one of these overlays. So easy and it stays through showers, swimming, hiking all week in hot weather. It is flexible so it is easy to place on the sensor in the middle and gently smooth it on the skin without bubbles or wrinkles. The backing of the tape is not perforated well so just take the backing off all at once. And I have repositioned the tape after it was on my skin and it went back on fine and stayed the whole week just as well. Because it is so easy to remove, I even took the patch off once without affecting the sensor, unplugged my transmitter and reinserted it and put another patch on and all worked without having to replace my sensor. Excellent!

They work well, but it is difficult to remove the backing.

Have only used 2 patches and not impressed. They Peel up easily which causes them to catch on clothing always afraid I’m gonna rip it off along with the CGM. Very disappointed

Used with 14-day Lingo, and they usually last about 7 days. Edges start to come up and ravel, waterproof-ness is questionable. Comfortable, can’t say I’ve had any serious skin irritation. And much easier to apply than some of the others. They’re “just ok”.
