I have no trouble with any hovabator, I have fanned and still air. Works best if you fill them up, though. If your only setting a few, but in baby food jars full of water. They will be nice little heat sinks to keep an even temp, and have a bonus too.... If you want to know the temperature inside your eggs, you simply take the temp of the water (with a human thermometer) inside the baby food jars. It will tell you if you need to panic or not if something has gone amiss with the thermostat. Usually setting lots of eggs or adding heat sinks prevents temperature spikes.
Naturally, I prefer the full bater method.
