Still, it's not on a thermostats as you can't place a probe on them. It's playing with danger. Plus he doesn't plug that particular one. Some kid watches the video, goes to some smaller expo and finds a guy selling a 5 buck used head rock. To me it's still a nightmare waiting to happen. There are enough errors with the cheap thermostats and that's on a rhetrostat. How long until we start hearing about burbs on those rocks? Not just that but a humid hide, which is fine, but with a light on non stop and a screen top do you really think the snake would live a long healthy life like he says?
