I loved the patch appearance. The design of the backing needs to be in 3 pieces, not just cut in half. A larger section up the middle, with 2 smaller sections on either side. That way you can remove the center strip, place the cover on the sensor and then remove the edge pieces 1 at a time by folding back and pressing down. It also keeps your fingers from touching the adhesive. I also do not like the adhesive sticking onto the sensor in the middle. I cut the center non stick portion out of one of my clear sensor covers and placed it in the center of yours. I then placed the Stick to Hope Christmas cover onto my arm. That way its not sticking to the sensor itself in case I need to change the cover and not accidently pull the sensor out. Surprisingly, the cover stayed on for 8 days without rolling on the edges until I needed to change my sensor.
The material is great, as it is sturdier than the previous ones I was using which were very thin and rolled up on edges and had to be changed 2-3 times in a 2 week period.
I enjoyed trying this product. I have 4 more to wear.
