There are a lot of bad reviews about those incubators i think someone got the best results laying it on the side not only did it increase the size of long containers you can put in but also maintained internal temps better due to fan placement. Sorry but just me I would either send it back and get a hot box or go with a homemade if you dont believe me look up the reviews yourself I would just feel bad if i either cooked them or froze them...Just saying.
