So they seem pretty good, but I have a few things to talk about. First, each of them gave slightly different readings. Second, that the humidity and temperature sensing holes are on the back where you would place the double-sided foam. Third, to get into the battery compartment, the door must also be foamed in at the back. My solution to rear panel issues would be to cut the foam so you can access the battery and not get in the way of the vent.
