This small disc really does what it claims to - the sensor is well protected and stays in place for 14 days.The small petals ensure the tape has something to stick securely to. It would be great if Libre had them on their website- as everyone using the sensors needs this product.
Great idea but the patches that come with it aren't big enough & the "petals" poked through. I changed to a different patch which is slightly bigger & it seems to be working better.
They are very sticky and the plastic flower seems to be securing the freestyle sensor lasting well over 7 days
