This one is what I have in one incubator, works flawlessly with 2 60w blubs, checked last night with the spotcheck thermometer and it's set to 37.5 C with a swing of .1 C. I don't doubt those ones that you have work, they look pretty solid I have a cheaper version of that but it's only accurate to .5 F and I didn't like that so i bought these ones, Water heater does fluctuate a lot but it's a set it and forget it once it's done. Have you ever used the humidity controller that's in the same sort of enclosure as the one you linked? I have 2 of them but stopped using humidity... just do dry hatches now.
