Please dont take this the wrong way, I dont mean it as an attack at all, but I feel like this is worth mentioning.
This reason is exactly why the frequency neglected topic of minimum neccicary wattage is so important. Thermostats fail. Some brands/types more then others. Some have safety features, some dont. The best safety measure in the world is appropriate wattage. You want the smallest amount of heating output possible to still get the thermal gradients you need, and no more. In the event of thermostat failure, your animals are only mildly overheated, instead of dead. All my set ups are run on stats, and before any animals move in I know exactly how hot that setup can get unregulated, and it is never enough heat to kill anything. I dont know why no one ever talks about this, but I think its very important
Btw I learned this concept from the boaphile
