The Best Cover for Dexcom or Medtronic’s Guardian
We’ve tried them and most of the patches get wet, are difficult to apply or uncomfortable. This brand is the best one we have tried. Very reasonably priced.

Second time purchasing these for 780g Medtronic Sensor/transmitter over patches. They have never come off in 7 day periods of time

price
This item is OK but it's not top quality when I buy them again I would say no but for the meantime I will keep them.

Awful product!!!
Bandaid would be better than this crap. This is after the 4th piece used. It doesn't stick at all. I've been using a CGM for 6 years so yes I know how to properly apply. Awful awful awful.

Not very good
It wasn't easy to get on and it would constantly stick to itself

Not bad,just be careful with applying.
They serve their purpose, rather difficult to get parts of the backing off, so be cautious, might cause it to stick to itself.

Great adhesion
These are way better the what comes included in the guardian 4 box. No residue on the transmitter and sticks great to me.

Don’t bother!
Absolute garbage product. Does not stick and is definitely not made for skin. It isn’t flexible and is just a piece of plastic with sticky glue

Size
The size is great but the sticky texture doesn’t work well

Meh
It barely covers the captor and the transmitter,I mean the non stick part is not big enough to cover medtronic's sensor and transmitter when they're on the back of your arm. It doesn't stick very well in the skin most of the time. When it does it's great. But I need a couple try before the applied look looks like the pictures. I'm not satisfy with the product. I would not recommend.
