Yeah I would never put eggs in the hands of Amazon

. Well good thing you had some sort of back up plan. After trying a Exo Terra incubator for a year with bearded dragon eggs and seeing how inconsistent. I didn’t want to take that risk with Cham eggs. I decided to build my own. And has been going strong for 2+ years now. I can’t recommend Herpstat SpyderWeb thermostat enough it’s very accurate and reliable. And just like your thermometer that gave you a warning

the Herpstat will do the same and send you alerts.
