I'm currently using flexwat but I was previously using Zoo Med UTH's, during that time I was using the below duck tape to adhere it to a glass enclosure, I was very generous when applying it, never once had an issue, the temp rating for duck tape is 120 degrees.

Hot glue wasn't the issue. The UTH is self-adhesive...peel off the paper, and the glue is there to adhere to the underside of the tank. If the probe is between there, how hard will it be to get out? Plus, how much glue residue will be left on the probe? That is what my concern is.
