Mine holds the temperature within a degree or two. However humidity is a constant issue in the house with the AC running.The bottom is not water tight and the small channels they provide to hold the water need to be constantly monitored. If you use one incubate on Sphagnum moss to hold the moisture bettter.

I can not speak directly about bearded dragon eggs but I can tell you that the incubator does seem to keep the temps fairly constant. I have snakes and I place the eggs in containers with damp perlite that then go in the incubator. humidity is my main issue. I have to add water to the incubator every day or two to keep the humidity in the 70-80% range

Bought it for snake eggs-Gonyosoma but while waiting for the Gonys to lay we have had several clutches of Leopard Geckos and so far its been a total wash. I have always incubated the eggs at warm room temperatures (around 80-90f) and had good results. We incubated on perilite. We set i[ the new incubator at 86f and it seemed to hold between 84 and 88f. We used damp sphagnum in tupperware type containters that we cut the plastic tops and glued wire mesh in instead and the eggs fungused. We are getting ready to try another set and use perilite We will see if that makes a difference.

You will need to purchase the trays or containers for the eggs separately.

We have successfully hatched may animals of different species in these incubators. While we do not breed any snakes, I know several breeders that have had great success with hatching Ball Python in the Reptibator.

yes

Yes. I used it to successfully hatch red eared sliders. I also successfully used it for hatching Russian tortoises.
