Wow Jordan, I was thinking about that the other day when my heat emitter stopped working. I went to look at Pio and he was on the oposite side of his enclosure sleeping. The HE over his hide went out and it was 70 on that side. I had to run out and get another one. This time I bought 2 just in case this happens again. If there isn't anything like that you should invent it.....I would buy it for sure. It could go off if the temp. drops too low or raises too high. I wonder........
