Nate, frankly I was gonna get in on this till I saw it all headin' downhill. The resons stated for not using heating pads are all valid. They have been known to start fires, the three level controls on most either get it to hot or not quite warm enough. Now, that being said, I used the same human heating pad under the tank I keep my pair of ball pythons in for eight years before it burned itself out(running 24/7). Never overheated, no burns, no fire. I don't tend to use them for my lizards, just my snakes. I suppose you could hook a thermostat to one and have better control of the heat, I've just not bothered. They can be made to work, but they just aren't the best choice. Use your own judgement, but be aware of the dangers. Just my thoughts.
