It's actually reading around 100 IN the tub, if I put the temp gun directly over the hottest part of the flexwatt - but on the other side of the tub (where the probe is), it's only 90-95 right over the tape. Weird!
I guess it's fine if only that one spot is hot, since hopefully she knows how to thermo-regulate herself. Right now her flexwatt is connected to one of the racks, so I can't turn it down much without freezing my corns.
