  • Small but fully functional
Grabbed this unit for my veil tail Betta fish that happily resides in a 3-Gal fish tank. Since the moment I placed it in (with good water circulation), she started swimming towards it and enjoyed circling around it. This fish-tank heater has been working steadily and able to maintain a stable and ideal temperature that makes my Betta happy and stay healthy. Just one advice, please check and clean the heater periodically, the basic maintenance is still needed. ... show more

  • Nice heater
Nice simple heater. All you have to do is plug it in and it does the rest. It keeps the water at or around 78 give or take a few degrees. I have bought a few for my tanks and will buy more when needed.

  • Great for small tanks.
I wouldn't go anything larger than the stated 10gal capacity, it won't be able to keep up.

  • One Temperature
Works fine but there is only one temperature setting and it is a bit warmer than I wanted. Worse fine and certainly not to warm so I am using it.

  • Works great!
I have had this water heater for a little over two months now. It turns on and off just like it says and it keeps the water temperature in the proper range. Highly recommend.

  • Not too big to hid in the plants
You don’t even notice this. Do easy to use and suctions in place and not too hot or too cold. We have happy little fishies

  • My betta is much happier
He was really stressed before and got spots. They went away once the water was consistently warmer with this.

  • Stopped working
We used the unit for our Glofish tank. Worked great for the first 3 weeks but now the tank is about 71F which is the same as the room. I would not recommend this heater.
