"5 degrees."

It took me only two tries to get it to the correct temperature. I will definitely be buying another one for my other tanks at bigger one. It's pretty noticeable, but I don't really care. And I get to keep the first one I bought! They promptly fixed the issue without any delays or drama. Also I like how it shows both the current temperature and the set temperature. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees.

"This heater is excellent."

Will update my review if any changes occur. But my guys don't read them and don't listen! The heater is being used in a 40 gallon breeder. Once I opened the box i noticed the quality of the construction. Personally for me the housing doesn't bother me. Ick for instance detaches from fish at 86 degrees and dies at 89. Also I like how it shows both the current temperature and the set temperature.

"9 degrees."

Would be great to be able to tune that to. But I am single and don't have to worry about this. --The heater itself is a bit shorter if your tank is a short one. I recieved this product without the instructions or the added thermometer. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. Keeps the temperature within 1 degree of what you set it to at all times. I like the fact that it comes with a digital thermometer.

Well worth the money the first one I bought still works great. I dont know, and havent tried just yet. Personally for me the housing doesn't bother me.

Would be great to be able to tune that to. I would definitely recommend this product. I got this heater for my 55 gallon aquarium. And I get to keep the first one I bought! Bought it as a chiller for the k40 CO2 laser. But my guys don't read them and don't listen! Very easy to install and the adjustable temperature gauge is pretty accurate.

"7L Imagitarium tank."

Easy to read the temp and know exactly how warm the water is. I emailed the email it says to and told them. They promptly fixed the issue without any delays or drama. The controller is easy to use, very accurate and reliable. No biggie, but annoying nonetheless. When i installed them, i let them sit in the tanks without power for 6-24 hours. My marina heater takes a few hours.

"This is a quality heater."

I have 3 of the Fluval heaters, in various sizes. It's pretty noticeable, but I don't really care. We received the chiller promptly and put it into use. Just be careful and keep an eye on your temp settings when you have kids over! This heater is NOT fully submersible. No biggie, but annoying nonetheless.

"Looks as advertised."

I got a hold of Amazon, who put me in touch with the seller. Once attached to the tank wall I've had no issues with it coming off. I adjusted the set temperature a little lower to be more in the range I wanted. --Temperature adjustment labeling is on top rather than on the rod. I had a thermometer on opposite side of tank and the heater was dead on true. --The cylinder or rod diameter is bigger. But my guys don't read them and don't listen!

7. Famus Aquarium Fish Tank Heater Protective Case Detachable Designed Cover with Suction Cups(42.5 cm)...

Famus First Impressions

"Seems very well built."

It is a bonus that the heater is titanium. If the blue light is flashing it means the heater is not fully submersible. Once attached to the tank wall I've had no issues with it coming off. Pressing and holding the button for 5 seconds changes it from F to C readouts. There is a misconception on the internet that the heater isn't fully submersible. I like to keep it at 72 and from my thermometer it is reading at exactly 72. You don't have to worry about wide temperature swings with this unit.

"Easy to unpack."

This heater warmed it right up and now my Betta and guppies are more active. My heater is fully submerged underwater and works perfectly fine. I bought a similar one at the pet store and it barely worked. The temperatures are pretty accurate. Temperature is slightly off by running a little warmer. I use a 50 for a 5 gal and a 10 gal tank. I got this heater for my 55 gallon aquarium.

"Well written but vague."

We would consider a replacement and then we would return the defective unit. Once attached to the tank wall I've had no issues with it coming off. This this is amazing and is worth the money. Also were nice along the whole process. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. The heater is super thin and the reflective surface is interesting. So if you set it to 78 degrees, the heater will not kick on until it reads 76.

This heater warmed it right up and now my Betta and guppies are more active. The temperature lights up so it's very easy to read. Maintains it well except when the weather is already warm then it over heats it. The bonus digital thermometer it came with has been super helpful, and is accurate.
