This is the first aquarium heater I've ever bought. I got my first betta fish, and since we live in a colder climate definitely needed a heater for his tank. I was worried about this from some of the reviews so I got a thermometer for the side of the tank as well. The temperature seems fairly accurate and I have only had it for a few weeks but it seems to be working fine. I think Mr Pokey has doubled in size and that time frame he seems to like the heater, he likes to swim around it. So far so good!
