I posed the same question about that exo terra about 6 months ago and most of the responses were its way too small for Python eggs. Another member here " Diaggia" recently used it . A much better product is Zoo Meds "REPTIBATOR " bc it has a built in proportional thermostat. I just used it recently and it is a fantastic product that is very reliable and is used by a few zoological institutions and other reptile facilities.![]()
