40 Pack for Medtronic Sensor Patches，Waterproof Guardian 4 Sensor Cover Patch，Hypoallergenic Pre-Cut CGM Sensor Patches Protect Your Sensors Continuously for 7 Days Long Stay

A bit tricky to apply, so have to get my husband to do it for me however they are so much more comfortable than the patches provided with my sensor and much kinder to the skin

These patches are not nice - very hard & inflexible. Bought to cover Guardian G4 sensor but not fit for purpose.

I have found these patches just right.They are large enough and have sufficient adherence to provide secure fixation of the sensor.They are relatively easy to apply even on the triceps area (posterior upper arm) .They are available at a reasonable price and unobtrusive

I have been using this for a while and definitely works!Keeps my sensor on and it's easy to remove.

My wife uses the Medtronic Guardian 4 CGM sensors, but has had problems with water leaking under the adhesive patches that come with them when showering. She had been using Tegaderm branded patches, which cover the entire sensor, but even these are not completely waterproof, so seeing these patches we thought we would give them a try. From the description it appeared as if these were going to be larger than the Tegaderm patches, but they are, in fact, slightly smaller. The patches themselves are also very fiddly to apply, due to the paper covers causing the patch to pull and twist, causing it to stick to itself, and once that happens there's no going back and the patch has to be thrown away. I fit her sensors and apply covering patches, so I'm used to dealing with these kinds of things, but I found the application extremely fiddly and problematic. After a few tries we got one covering the sensor, and my wife tried it in the shower, however water still leaked through under the surface of the patch. She has had to resort to wrapping her upper arm in clingfilm to try and keep the moisture out. Upon trying another patch, she wore it during a particularly hot day, and found that it eventually worked loose due to sweat accumulating under the surface.

These fit well and stick well as advertised.Perfect for use

These both seal and hold onto the skin really well.They are waterproof and they do as promised hold on even after showering or swimming. They are very easy and quick to apply and they don't irritate the skin as they are hypoallergenic and latex free. Would have been nice to have had more in the pack but good so far.

Waste of money.
