rant anytime! they make the spot check and it is spot on for us! I use this to calibrate all and my children
you read about the still air temps and what level you need to check it correct? lets ask Rav on her input on these eggs shipped ok? @RavynFallen
Go ahead and rant, Moo!
I have had to recheck and recalibrate just about all of my thermos each time I use them.
I have and old, well ok, realllllly old medical thermometer that I use as my standard, hasn't failed me yet.
The new stuff seems to be produced for quantity over quality, but once you get them figured out, it does get bearable. You just have to keep in mind that they are a little 'off' and adjust for their inaccuracies.
As for the duck eggs, I agree with Sally, Ravyn is the one to ask. I let my ducks do their own, tried once in incu, failed all 12.
