Excellent product! Will definitely order again. Waterproof and perfect size.

These are great to make sensorwaterproof

I was having a lot of trouble with my sensors falling off or me scratching them off by accident etc etc. this has completely eliminated that problem and the price was very fair. it doesn't interfere with anything I do.

THESE Waterproof Freestyle Sensor Covers for Libre 3, blue Latex-Free Medical Adhesive Patches for Libre 3 do not work for Libre sensors as they completely cover the sensor hole. This causes moisture to build up under the sensor causing numerous sensor errors and eventual sensor failure. The workaround / fix I used was after application of the sensor cover over my Libre 3 sensor, I used the tip of a toothpick to poke a small hole in the plastic cover ensuring and inserted it only far enough to create the hole. Another option would be to use a paper hole punch to create a small hole in the cover. Easy to do if you lay the cover on top of the sensor the the adhesive gaurds still in place a use a marker to indicate the whole in the underlying sensor. Then use the punch/

it works for what it needs to work for but if it's on your skin too long it leaves a burn mark around the sticky plastic part

Not easy to peel the second layer back when you have sensor applied to back of your arm. (The layer with the blue strip.) I would think someone could come up with a better application design.

Not at all a good product. Save your money. Get something different. Doesn't work at all

This is a horrible product. I cleaned the area around my CGM implant then dried it off and applied the patch. It fell off in 4 minutes. I waited 20 minutes to make sure the area was dry and applied another, it lasted 15 minutes before it fell off. For the heck of it, I put one on just before bed and it got tangled up in my blankets in about 10 minutes before. This is close to the worst product I've ever bought. Stay away.
