Zoo Med habitat heater... Any experience?
 

I was watching youtube vids the other day and saw Peter Birch using zoo med habitat heaters for his blue tongues in their outdoor enclosures. I was curious, who has experience with these? I'm debating ordering one to test out how well it works in various situations. Thinking they could be great alternatives to boost ambient heat as well as providing a large hot spot.
