I recently discovered Tegaderm to cover the freestyle libre. I don't know WHY they leave it to you to discover how to properly secure the device, it DOES NOT stay put for 15 days unless you don't bathe.
Anyways, the Tegaderm has several advantages over the large bandaids I was using before, it is transparent, it breathes, and it causes less skin damage.
I have found the Tegaderm lasts less time that some of the bandaids I was using, perhaps 3 days max, and one single bath will kill it. I am staying with the system because it has other advantages.
To take the Tegaderm off without removing the sensor, I hold down the sensor and pull up an edge a bit up over the sensor. Then I hold the sensor down on the uncovered part and pull it all the way off. It takes practice, but is doable.
