These aren't as fancy as many on the market. These are plain translucent tape with no fancy designs. The samples arrive with no instructions (although they aren't hard to figure out) and no ordering information (I guess Lexcam assumes you remember where you ordered the samples). I found them a little awkward to apply since you are applying them one-handed and possibly in a location you can't see (if you wear your CGM on the back of your upper arm). Of the three samples, one didn't seem to stick all the way around, but it still worked surprisingly well. I've only been using the Libre3 CGM for 3½ months. I've gone through 15 sensors - only four of which lasted the full two weeks. But since I started using the Lexcam patches both sensors lasted the full two weeks with no problems. That was enough to convince me -- these things work. I am much more confident that the sensor won't come loose or fall off now.
