I noticed that too...also, I usually tape the probe to the bottom of the enclosure so I get a surface temp near the hide (or I place it right under the hide near the edge).
you wanna send me some of those boxes ! I have been looking for them for a while lol
I found that Target has a better selection of Sterlites than Walmart....I know, I'm a traitor!! We had been trying to find a box that wasn't too deep but had more length, and we found what we were looking for there. Relatively inexpensive, about the same that Wally World charges.
