I seen these and thought I would try them... For me, they worked just as they said they would... They didn't irritate my skin... They were water resistant and I didn't have any problems with them rolling up, even with wearing it for 14 days... Now the only problem I had was, once I took the cover off, my sensor stuck a bit too well... I liked to never have gotten thang unstuck... Will that stop me from using Flexd, why no, not at all... Review: A Must for Freestyle Libre - Purchase these for my boyfriend who was having challenges, keeping his sensors on. These are especially great since they do not have any adhesive in the center; this allows you to peel the patch off and replace it without dislodging the sensor. Before purchasing these, he was doing good for a sensor to last a week. Now, no issues whatsoever with the sensor remaining in place for the full two weeks. ## Features - Protect - our libre sensor covers patches are very durable and designed to last.

All I read about how well/bad it sticks to the skin. Is it a monitor for blood/sugar?** A: It covers the sensor (Freestyle Libre, and others) which does measure blood sugar constantly. The sensor has its own stick-um, which is better by far than it used to be, btw, but it does tend to loosen over the 14-day period of use, especially those last two or three days after activity, sweating, swimming, showering, etc. The patch holds the sensor in place and does not in any way affect its operation (i.e., it does not affect readings from the sensor, using the meter which picks up the sensor via radio and displays the blood sugar readings). The patches stick pretty well, actually, and can take a little effort to remove, once you're changing to a new sensor. Careful not to apply anywhere on the skin where you've got hair - you may lose some of that hair upon removal! Hope this helps! **Q: Is there adhesive in the center?** A: Hi, the center of the patch is without adhesive. Hope that helps : ) **Q: Does this work with Libre 2 sensors?** A: Yes I have no issues with it it covers it up and can read the sensor **Q: Does this work for guardian cgm ?** A: These have a round spot in the center with no adhesive. This spot is the size of a freestyle libre sensor. This is what the product is designed for, if the guardian is that size and shape it should work, if not then probably not. I have only used it for freestyle. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked like they claimed... *by M***E on January 6, 2022* I have the Freestyle Libre and really needed something to put over my sensor so I wouldn't be pulling them out...
