I actually did a pretty thorough review of the Reptibator that you can see here: http://www.reptilescanada.com/showth...ew-amp-Fix-Mod
I have two of them, one as an emergency backup that is kept in the closet, and the other is for my hognose eggs since they like to be cooler than the ball python eggs that I keep in my large DIY incubator.
They can work quite well if you address their default issues.
