  • Tiny, great for nano tank
Size: 25W-5Gallon
I did just receive this today, so I can’t speak to longevity. It does fit so much better in my 3 gallon rimless shrimp tank than the smallest heater I could find at my local pet store. I have a hygger on my 29 gallon that of course is huge, but this little heater has the external control and thermometer just like my hygger. I really like that, so convenient to change the temp without taking out the device and fiddling with a knob on the top, and it shows the actual aquarium temp in large clear numbers. I will update this review if I encounter any issues with the device, I’m hoping not. ... show more

  • Not accurate at all
Size: 50W-10Gallon
The heater is very inconsistent with the temperature. It has a 4.2 degree difference from what it states versuses the actual temperature. I matched it against a professional gauge thermometer. Also, I can set it for 75 degrees and it will heat up to 79+ degrees. I really don't wish to turn my fish into fish fries. Honestly, I cannot recommend the heater. ... show more

  • These seem to work fine
Size: 25W-5Gallon
Very ease to set the Temp , seems pretty accurate. The 1st one of these worked good enough that we got another. I have yet to find a heater that says suctioned to the side for any length of time.

  • Holds temp well
Size: 150W-30Gallon
Bought these for my hydroponics tanks. Like the external temp control which is easy to read and adjust. Being able to place the heating unit very low in the tank is a plus. Only downside is if there is no rater movement the enclosed heater will not heat the water. A small bit of heated water is trapped within the housing which results in the heating unit turning off. If the warmed water could escape allowing cool water to flow in the unit would be much better for still water heating. With flowing water this heater keeps 30+ gallons at the temp set. I have three of these and would buy more. ... show more

  • Nice little heater....
Size: 50W-10Gallon
The media could not be loaded. I like that it has a safety cover on it so my African Drawf Frogs won't burn themselves... The suction cups don't stick very well but that's ok because it sank to the bottom of my 10gal tank & looks like a submerged submarine which goes well with my tank decor...
