    • works very well, EZ to install

very well made and easily adjusted temperature

    • Works great
Pattern Name: 50W
Works great in our 10 gallon. The dial knob at the top to adjust temperature can be a little tricky though. There is a 4 degree label gap between temps so you have to guess. Ex) 78-(gap)-82. So if you want 80 degrees, you adjust the dial in the middle of these two numbers. Not a big deal, but with me being new at fish keeping, I worried it wasn’t at perfect temperature. Other than that, it’s a good product! ... show more

This aquarium heater is keeping my tank at a steady temperature, and it was easy to set up. So far, it’s working perfectly, and my fish seem happy. I’m hoping it lasts a long time, but for now, I’m very satisfied with the performance.

    • Decent budget heater
Pattern Name: 50W
Had to go a few degrees higher to get the 76 I wanted but it heats and it works. Good heater if you’re on a budget. Update: only lasted 4 months and quit heating

    • Pretty good
Pattern Name: 50W
Love the heater. I am using this heater for my 10gal tank. The adjustable temperature knob is easy to access and set. I keep my temperature at about 80F and the tank's temperature stays at that value. I temperature strip is included in the product and it works pretty well.

I couldn’t be more satisfied with this aquarium heater! It’s compact, easy to install, and has been consistently reliable in maintaining the perfect temperature for my fish tank. Worth the price !

    • Too warm; too cold. Not switching between off and on?

Got this for a 20 gallon tank. The knob is excessively difficult to turn, but no matter what I set the heater to, the water temperature is never consistent. The other day, around 7am, I went through setting it up and getting the heater added to my office aquarium. I just have a mystery snail in there right now, so I figured I'd set it to 76 and see how it went. By noon, the water had hit almost 80. I thought at first that maybe the thermometer was wrong, but no - genuinely warm to the touch. And since I placed the heater and thermomenter on opposite ends of the tank (HOB filter in between) it may have been higher. So about four degrees too warm? Turn it down four degrees, right? I turned it down to 72. This morning the tank was 64 (or less; that's just as low as the temperature sticker can read). Puzzled, I bumped it up to 73. The light turned on and i could see the ripples as the water began heating. As of right now, 1:30pm, it's now sitting between 76 and 77 (climbing). I've checked the tank multiple times throughout the day and I have not seen the heating light turn off even once. If it goes past 78, I'm gonna unplug and return. ... show more

Weve had this for a few months with no issues. Our fish tank stays right between 78 to 80 degrees. Easy to use and set the temperature. We have it in the corner and doesn't take up much space. It also has a little orange light that shows you it's heating so there's no guessing.
