110V 300W 300-Watt Submersible Aquarium Fish Tank Water Heater with Built-In Thermostat

This heater works fine. I haven't had any problems. I would buy another one if I needed it. So far so good.

Please listen to these reviews, I know I should of did before purchased this cheap crap. My fish almost died using this heater. Where do I start? When I first put the heater in my tank it had my water temp bouncing from 7580. I prever my temp 78-80. It doesn't have a temp reading on the knob so you wouldn't know what your setting the temp at. I just turned the temp all the way up after I've had to guess which way it was, and it only kept my tank at the highest 80. Like I said it had temp swings in my tank. Gladly my fish didn't get stressed over that. So it been about a month now and yesterday when I walked in the room to turn my fish tank lights on. The temp said 72 degrees on my tank thermostat. I had a fit and was worried about my fish. I drove to the nearest lfs and bought a heater.Thats what I get trying to be cheap, like they say you get what you pay for. Don't be cheap, spend a extra15 -20 dollars and buy a good heater. The heater I bought from my lfs is doing the job, but I just ordered a fluval 200 watt for my 40 gallon. I heard a lot of good reviews about it.
