"The seller was wonderful."

I think it works well to not stand out like other heaters. If the water runs low or air gets in the heater shuts off. I have only had minor problems with the suction cups. They promptly fixed the issue without any delays or drama. This has the best controller that I have found on the market. I will be ordering more of these in the future. This is a powerful heater that holds temperature very well.

Fluval A782 Final Thoughts

"5 or even."

I will be ordering more of these in the future. I will definitely be buying another one for my other tanks at bigger one. It does blend well in some setups and may look bulky in others. We would consider a replacement and then we would return the defective unit. Thanks for the great customer service! Pressing and holding the button for 5 seconds changes it from F to C readouts. My marina heater takes a few hours.

"I got the 100 watt one."

Or better yet, conceal it to the back corner. They promptly fixed the issue without any delays or drama. I like to keep it at 72 and from my thermometer it is reading at exactly 72. It just cycles through to 93f and starts over. Come on Fluval, expect better from you. This is a powerful heater that holds temperature very well. I recieved this product without the instructions or the added thermometer.

Fluval A756 Final Thoughts

"Until the next time."

So when I first received it it didn't work and I was very disappointed. The heater is super thin and the reflective surface is interesting. Two inches above that is a waterline for maximum. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. So when I first received it it didn't work and I was very disappointed. Per my thermometers, they are all staying constant. I will definitely be buying another one for my other tanks at bigger one.

"I like this heater."

I noticed my old hygger heater beginning to fail and my wife ordered this one. The heater is super thin and the reflective surface is interesting. After several weeks of running the heater. Come on Fluval, expect better from you. Takes a little while to drop the temps if it is hot in the garage. We wish the controls were available in Farenheit also to make things a little easier. The heater is being used in a 40 gallon breeder.

"16-26 gallons 75 watt 10."

Keeps the temperature within 1 degree of what you set it to at all times. It's pretty noticeable, but I don't really care. I bought a similar one at the pet store and it barely worked. This is a great heater that is very easy to set up and program. And kids love pushing all sorts of buttons. 210 gallon ones and one 90 gallon bow front tank. Checked the accuracy of the heater with an infrared thermometer.

"Pricing was good."

This has the best controller that I have found on the market. The temperature lights up so it's very easy to read. I have a 10gallon tank that was at 72 degrees. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. Checked the accuracy of the heater with an infrared thermometer.

I like how the heater is constructed. --The cylinder or rod diameter is bigger. My heater is fully submerged underwater and works perfectly fine. Once I opened the box i noticed the quality of the construction. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. Would be great to be able to tune that to.

PERSUPER Final Thoughts

"Impressive."

Am a totally sold customer and would recommend them to anybody! I got a hold of Amazon, who put me in touch with the seller. Seems to keep the temp n the tank fairly regular. It comes with a hanging kit and can be secured on the edge of the tank. We received the chiller promptly and put it into use. It would stick out of my 30 g wide tank if I were to put it vertical. The design is sleek and modern looking.

"Very easy and accurate."

What more could you ask for great job Hygger Duncan. Very easy to install and the adjustable temperature gauge is pretty accurate. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. Beware, but we are hoping for a good outcome! There is no protection from it banging on the glass tank. My marina heater takes a few hours. The heater protector was very heavy plastic and slim lined which is great.

And I get to keep the first one I bought! We would consider a replacement and then we would return the defective unit. Also I like how it shows both the current temperature and the set temperature.

"Not very reasonable."

I like the fact that it comes with a digital thermometer. 210 gallon ones and one 90 gallon bow front tank. What more could you ask for great job Hygger Duncan. 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.

Once attached to the tank wall I've had no issues with it coming off. But I am single and don't have to worry about this. The cover over the heating tubes is great, the turtles claws can't damage the tube. And kids love pushing all sorts of buttons. The line is there due to regulations in certain countries.

I got the 200W variant for my 54 gallon corner tank that's housing goldfish. When i installed them, i let them sit in the tanks without power for 6-24 hours. This little heater is perfect; this is our third purchase of the same heater. So far I like it setup was super easy. They promptly fixed the issue without any delays or drama. I hope these suction cups work very well. The heater is easy; turn the dial to set temp and plug in.

Now, both points are clear on the package instructions. I use this little heater for my 10 gallon quarantine tank. The temperature difference was very minor.
