I did read it, a couple times to make sure I hadn't missed anything :x I saw how it attaches, just wasn't sure on the thickness and wondered how you got it to lay flat and not light things on fire :3 From the pictures it looked thicker, .5-1in to me, which is why I was wondering how to keep the thing from turning into a see-saw.
I did see "Radiant Heat Pannel: The thermostat probe will need to be secured inside the cage directly under the Radiant Heat Panel." but it doesn't answer the question of whether I'm plopping my probe on the substrate and that would be "directly beneath", or if I'm somehow wiring it up to be against the heat panel on the ceiling, or whether there truly is no risk of burning my snake as I've read countless caresheets that warn against putting heating elements where he could reach. We've already been through burns once and understandably I'm a bit reluctant to risk it again.
