2 Pack Reusable Hardshell Covers for Freestyle Libre 1 & 2 & Lingo Sensor, Prevent Compression Lows, Shockproof Waterproof Add-On Libre 2 Sensor Covers (4 Adhesive Patches Included)

I've tried two other patches to cover my sensors. I swim almost every day and found that the adhesive would give out before the sensor if left on its own. I tried two clear ones--they didn't really last the whole two weeks, so I would wait a while before putting the shield on and hope that I didn't knock it off in the meantime. And knocking them off was a problem--who knew I walked into door frames so often? Not me until I started wearing these! I've knocked sensors out after just two to three days of use. Doorways are the worst, but if I adjusted the location further back on my arm to avoid them, I would end up hooking and dislodging the sensor on the edge of my bed. So frustrating! The thin clear shields I was using didn't provide enough protection once I put them on. While they prevented me from ripping the sensor off my arm completely, they did not stop me from knocking them bad enough to damage the connection. With these shields, the plastic shield that fits under these is a great addition. It offers more protection from the knocks, but it also means that I can change the adhesive patch as often as needed without disturbing the sensor. I find that I usually need about a patch a week. The patches themselves feel more secure than the clear ones, are easier to put on, and are more comfortable because of the stretch in them. I considered deducting a star because they are also uglier and more noticeable, but I kept it at five stars because I'm so pleased with their overall performance.Update: I continue to like these better than any other sensor shield that I've tried.The plastic cover allows me to change the patch as needed without disturbing the sensor. I usually end up changing them after 7 days because the edges get a little ratty looking and start to come up. Since I'm going to have to change it when the sensor ends, I'll split the difference at a week, but it usually feels like they would have been secure on my arm for a few more days.I do find that my skin likes a periodic break from whatever they use for adhesive. If I wear too many in a row I will sometimes get a rash, but if I periodically wait a few days before putting on the sensor, then my skin doesn't complain at all. I give my arm a break from these every 4-8 weeks as needed.I recently bought a 10-pack tin of novelty patches from the company because I needed another cover and thought I'd add some fun/variety. The unit price of the novelty patches is about 3 times more than these, and I have had MUCH less success with adhesion. I'll stick with the basic model from here on out.

Strong hold even through shower, getting wet and sweating.

I like these better than the clear style. These last longer. The only negative is the cover sticks very hard to the sensor. If you need to change to a new cover any time during the two week sensor life, it is hard to pull it off the sensor without pulling the sensor off your arm. I cut a small piece of paper and put it in the center of the cover before I cover the sensor with it to keep it from sticking to the sensor.

This product works great. Especially if you pair it with the use of skin tac wipe.Even in heavy humidity in the summer it works.

The best part about this item is the hard plastic cover that it comes with. That really helps prevents any bumps or nudges from disrupting your sensor. The adhesive is not too extremely sticky (in a good way) but if worn too long, it seems to get stickier and irritating to the skin after a couple days. I wore it on a really hot day 100+ degrees and when I removed it, the adhesive pulled of some skin with it too. I would buy this for just the cover and keep searching for an alternative sticker or non-adhesive patch to use it with.

Tried it several times. Didn't stay stuck and left a rash on me. It itched the whole time I had it on. Might be great for others...

NOT WATER PROOF! Fell off in the first shower. Second patch lasted less than a day of normal wear. Don't waste your money

Nice product has been good each time on my third order.
