I put this in my turtle tank and it works pretty fast and well. At first he made some annoying noises, but after a while they stopped. Everything seems fine. The only problem is that it's a surrogate because I have a turtle that gets a little crazy sometimes. He likes to rip the thermometer off the sides of the tank and chew on the suction cups. It's a bit dangerous. However, what can you do? He's a turtle and the world is his punching bag.
