I'm an avid member of another forum and read the woes of someone who's throwing out their incubator in frustration and buying another with which they'll feel more comfortable. We just did the same thing, and I'm not sorry! I'm not sure, but it I'm wondering if incubators and their components (thermometers, etc) may be a bit like musical instruments. You rather, master them, making adjustments to their idiosyncracies...and yes, like instruments, some are WAY more forgiving than others, (imagine a home-made model!), and yet, even the most crude can produce a little music with tenacity. I know our new styrofoam one is much better than our toy bator, but I still spent half the first night regulating it and getting accustom to it in general. We now have four eggs in it. So... far so good. I'll bet, too, (like instruments) there are folks out there who wouldn't trade their 'whatever' model for the latest and greatest because they have learned to achieve great success with the one they love. Is this analogy at all accurate? Just curious.
