We use [3M Tegaderm Film Dressing] (Amazon.com), and we have to use Uni-Solve after 14 days to remove the tape as it’s still firmly stuck.
We have a cardboard template that we place the film on top of and with a scapel, we cut out the shape of the sensor/transmitter so that the tape doesn’t go over the top of it. I wasn’t sure why, so did a little research and found out that it’s not recommended because the transmitter/sensor can overheat if covered by the taps. Not sure if Tim has ever had that problem but it doesn’t sound like he has.
I’m also reading some posts about moisture collecting under the transmitter when tape has it fully covered, but no one’s really indicated why that would matter.
There are equally, or more people on this, and other forums who cover their full sensor/transmitter and report having no issues, so it sounds like a case of YDMV. I don’t find the cutting out of the hole using the template to be a time consuming thing (10 - 30 seconds), so I just do it that way.
