I have some UTHs with the adhesive, & find they dont' stick all that well to Rubbermaid containers. Last week I bought a Cobra UTH & it has no adhesive so you tape it in place. Hopefully that will work better. Are you saying its ok to use regular adhesive tape on those other UTHs too? (The Cobra UTH has an area of plastic all around the outside so the adhesive tape is not actually over the area that gets warm - I wasn't sure adhesive tape would work so well if placed over the part of the UTH that is actually getting hot).
