I would suggest getting a cheap-o styrofoam cooler and placing the mini-bator in there to help regulate the temp. Keep the lid cracked and poke a few hours hear the bottom of the cooler so you get the thermal airflow effect. this will help with the temp. These are really toys and should not be relied upon as real incubators. While they can be made to work, they fail quite often too. Hope this helps and keep us posted.
