    • Works GREAT
Size: 25W: 1-8 gal
This is a great heater. I have a 4.5 gallon tank. The suction cups are fantastic. It came with a thermometer sticker that is very accurate, great feature. The heater will turn on and off to make sure your water does not overheat or underheat. It was very well packaged, no breaks or cracks. Very easy to use and set up. ... show more

Works great in my nano tanks. I keep guppies in my nano tanks and the DOMICA 25W Small Aquarium Heater keeps a constant 78 degree temperature. Works great, nice product.

    • It’s awesome but question!??
Size: 25W: 1-8 gal
This is a wonderful heater for $9. The only (which are minimal) - temp gauge seems a little off but I don’t know if it’s me or the instructions weren’t clear. When you turn the knob, it shows a number inside the circle , is they the current temp or next temp? I only ask, because I know what the obvious answer is, is because it did seem a couple degrees off the “circled” degree and more accurate to the next degree after the knob turn. I just use that rule as my guide “the degree in the circle is the next degree after a turn” . Which, yeah the knob is slightly hard to turn , but not too hard that you need to leave a one star review because you don’t have enough common sense to wash the grease/oil off your hands first or grab a (clean!) paper towel first. It’s not the knob, it’s the fact that the water (assuring you cycled and are filtrating correctly) are simulating natural water flow and pulling the oils and impurities from your skin, and what is not natural to natural water sources and it’s inhabitants is people sticking their gross hands in them and wondering why their fish died. And also, it’s a nine dollar heater. It’s perfect for the price. I’ve yet to get to my real question thought because I had to vent. 😂 Anyways, can I bury this in my substrate? ... show more

    • Doesn’t work
Size: 25W: 1-8 gal
Item was marked as new but appears to have been refurbished. Also, described as “mini”, yeah if you have a 100 gallon tank! I have a 5 gallon for my lone betta and it fit inside, but was bulky and not enough room to submerge (per instructions). Specs are ~8 inches in length. Aesthetics aside, the heater didn’t even work. The light came on and appeared to be warming but after 10 minutes it completely clonked out and would not reheat again. Now I have to delay putting Betty in her new home another day! So annoyed !! ... show more

    • Incredible
Size: 25W: 1-8 gal
Amazing! Bought a name brand thermometer that actually made my aquarium colder! Bought this little guy and within 30 minutes the temp had gone up 10 degrees. By the next morning, it was to the optimum temp I needed to start adding fish. I'm so pleased. Great product for an incredible price!
