Well ill admit it Im a mother hen when it comes to incubating.... If I could sit on the eggs I would lol. Anyway as he title says digital therms suck. Went to wally world and picked up a digital therm/hydro combo. Got home and after an hr it topped out at 88 deg... not cool. After another trip the hydro didint work. (Enuf allready !) One more trip and I bought the indoor outdoor model. And now the hydro works but the temp is slooow in changing and the temp is 3 deg off. I have a 99 cent liquid as well as the original brower mercury. They both react fast and are spot on. ( checked with instant meat therm) Why cant anything be made quality anymore? Anyone else have thermometers off or hydrometers for that matter?
