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.

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.

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