    • Temperature reading doesn’t work
Size: 100W(for 5-13 gallon )
The temperature gage consistently says the tank is 90+ degrees and won’t heat the water. The water is cold to the touch. I have it set at 78 degrees and it says the actual temp is 85+ or beeps saying “HH” (which is what the device does when it reads that the water is too hot). Have unplugged, cleaned, tried everything possible to reset. Won’t change. Gave me a dud ... show more

    • Great Digital Heater
Size: 300W(for 26-53 gallon)
Review Image by AWL AWL
I really like this heater. The temperature control hangs outside the tank so it is easier to adjust. Easy to read with large numbera. Only thing I would change is the length of the cord from the temperature control to the outlet. But all in all it is great!

Seem like this unit last ight past it's warranty return Window. Thermostat always read falsely high about 8 degrees but I monitored that with a secondary.

    • DO NOT BUY.
Size: 500W(for 53-79 gallon)
Heater is fully submersed and is switching between error codes hh and ll and is not heating the water. Unit has failed after less than a month of use. UPDATE: Bought a 2nd heater and it also failed.

    • Had a hard time keeping correct temp, very large for my tank
Size: 100W(for 5-13 gallon )
I have a 6 gal tank so fairly small but the 50w heater I got previously seemed to be having a hard time keeping the temp up, so I decided to try this 100w. First of all it was a little too long to fit into my tank. The top of it stuck out a cm or so while touching the bottom of the tank. I did like how it has an external temperature control setting and reading box. It has a “actual water temp” and “set temp” so you can see where you’re tank is at. It seemed to me that I had to set the temp a few degrees higher than I needed for it to get to the temp that I wanted. I have a small filter and air stone circulating the water and since it’s a fairly small tank I thought that was enough. But it didn’t seem to be. I had a really hard time keeping the tank consistent. But it is nice that it has a beeping alarm that goes off when supposedly your aquarium is too hot for any fish. I’ve had this tank for several years so I have a hard time believing that it was anything I did wrong. I just don’t thick the thermometer was very accurate but I liked the design. ... show more
