“AddendumBoy was I stupid. I didn’t realize that I needed to remove the hard inflexible top layer of the patch.Once this layer is removed, this patch is great.Will I buy it again? YES!!!This patch fits perfectly and is easy to apply.My only complaint is that it is somewhat stiff and rigid. If doesn’t “flow” with the skin’s movement. Also when touched, it makes a crinkling noise.I guess what bothers me the most is that it constantly reminds me that I’m wearing itAddendum - My first patch after less than 24-hours is beginning to start coming off. I think the problem is that it is rigid and inflexible, so when I make any stretching movements, the patch doesn’t follow with the skin. As a result, it starts to dislodge.Another but minor issue is that it is very glossy and in the light quite shiny. If your Dexcom is not covered up when you are with other people, this patch now makes the Dexcom unit even more noticeable”
