So far I’ve had zero problems with this heater for my tank full of tropical fish. It keeps the temp at a constant 79.2 degrees and hasn’t wavered since reaching that. Automatically kicks on when it needs to heat up the water and a little red LED shows that it’s working. Turns off automatically when it’s reached temp. You could get one with more features like the ability to set the temp yourself, etc, and if you need to do that, this isn’t the unit for you as it features no ability to set a different temp than what it come programmed with. But for me, this is doing perfect in my 10 gallon tank.

Works awesome, holds my 10 gallon planted tank at a steady 79°-80°. Only had it a couple months, so I’ll return later on to update my review if anything has changed. For now, would order again

Got this for my 7 gallon, it sits about 77 to 79 degrees. Green light when off and red light when heating

I bought this because my fishes generic, unbranded heater decided to kick the bucket one night while I was asleep. This came and since has done a great job. However, it keeps the tank at five degrees above the temperature inside your house so if you don’t have great heating, not ideal for winter. Otherwise, it works fine.

Works well to keep temperature within healthy range for most fish. Suctions well to tank. When the light is green, water temperature is stable. Light shines red when water is heating.Have not had issues with this breaking and it has lasted a long time. It regulates the tank temperature well for a cheaper product. However, some fish like it warmer and you cannot adjust the water temperature with this device. But this is good for beginners starting fish keeping. I keep it as a backup to use if my adjustable heaters break.
