Very easy to adjust, and extra layer of protection for the adhesive
I'm doing a 14 day "test" to adjust insulin doses, as I wait for my own Freestyle Libre to arrive (got approval paperwork last week).  I am always skeptical of adhesives (either allergic, or they fall off).  While the adhesive seems good, I wanted a 'bump guard' type of thing, and this is very handy. I don't feel it 'squeezing' my arm, and it hasn't moved, and stays right over the adhesive, leaving the sensor open so the reader has no problem working with it.  I'm glad I ordered a second green one, and just sent for 2 pink ones.
