"Overall happy."

I will definitely be buying another one for my other tanks at bigger one. Just be careful and keep an eye on your temp settings when you have kids over! This heater is NOT fully submersible. The controller is easy to use, very accurate and reliable. I wouldn't buy any other heater, unless one of these stops working. The suction cups are large, high quality and seem to stick great. The temperature gauge is fairly accurate in my 55 gallon tank.

"9 degrees."

The temperatures are pretty accurate. Awesome chiller, perfect for Hydroponics. The heater is being used in a 40 gallon breeder. What more could you ask for great job Hygger Duncan. They shipped us the upgraded version that also heats! Come on Fluval, expect better from you. I like to keep it at 72 and from my thermometer it is reading at exactly 72.

"They contacted me."

You program it for temperature you want your tank to be. We received the chiller promptly and put it into use. I hope these suction cups work very well. I used to try those other cheap heaters sold on amazon. Seems to keep the temp n the tank fairly regular. The red light means it's off, blue light means the temperature is constant. The cover over the heating tubes is great, the turtles claws can't damage the tube.

"1 difference."

This product came in the nick of time! Those turned out to be a hit and miss. I have a 10gallon tank that was at 72 degrees. Come on Fluval, expect better from you. Well worth the money the first one I bought still works great. It is safe and dependable and comes with a one year warranty. For Discus you need warm and accurate heater and this seems to do the trick.

"Thank you for reading."

Personally for me the housing doesn't bother me. --The heater itself is a bit shorter if your tank is a short one. Thanks for the great customer service! I got the 200W variant for my 54 gallon corner tank that's housing goldfish. There is a misconception on the internet that the heater isn't fully submersible. I tested it by unplugging and replugging it. Also I like how it shows both the current temperature and the set temperature.

"Works fine."

210 gallon ones and one 90 gallon bow front tank. This heater is NOT fully submersible. This is only day one though, so I shall keep an eye one it. Per my thermometers, they are all staying constant. Once I opened the box i noticed the quality of the construction. This is only day one though, so I shall keep an eye one it. This this is amazing and is worth the money.

Very easy to install and the adjustable temperature gauge is pretty accurate. Two inches above that is a waterline for maximum. This is a great heater that is very easy to set up and program. The temperature difference was very minor.

"Overall happy."

At this time I highly recommend this product. I wouldn't buy any other heater, unless one of these stops working. The controller is easy to use, very accurate and reliable. Personally for me the housing doesn't bother me. So if you set it to 78 degrees, the heater will not kick on until it reads 76. --Temperature adjustment labeling is on top rather than on the rod. The heater is being used in a 40 gallon breeder.

"This heater works great."

The red light means it's off, blue light means the temperature is constant. It does blend well in some setups and may look bulky in others. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. This does a great job at regulating the temp in my 10 gallon. This heater works, but the dial it isn't very accurate. My heater is fully submerged underwater and works perfectly fine. The bonus digital thermometer it came with has been super helpful, and is accurate.

"I have a 5."

I appreciate the exterior temp readout and control module. I will definitely be buying another one for my other tanks at bigger one. I adjusted the set temperature a little lower to be more in the range I wanted. What more could you ask for great job Hygger Duncan. The heater is being used in a 40 gallon breeder. When i installed them, i let them sit in the tanks without power for 6-24 hours. Temperature is slightly off by running a little warmer.

Once attached to the tank wall I've had no issues with it coming off. For Discus you need warm and accurate heater and this seems to do the trick.

Keeps the water consistent and it's easy to adjust! The setting always stayed the same.

"It easy to set."

Seems to keep the temp n the tank fairly regular. Maintains it well except when the weather is already warm then it over heats it. Also I like how it shows both the current temperature and the set temperature. I contacted the manufacturer and they sent me a new unit in less than a week! The temperatures are pretty accurate. Am a totally sold customer and would recommend them to anybody! I think it works well to not stand out like other heaters.

I had a thermometer on opposite side of tank and the heater was dead on true. No biggie, but annoying nonetheless. You program it for temperature you want your tank to be. Sometimes it gets outside of it's ability to cool but only within a few degrees. Two inches above that is a waterline for maximum. I recieved this product without the instructions or the added thermometer. This product came in the nick of time!

"Until the next time."

I wouldn't buy any other heater, unless one of these stops working. Easy enough to let it run all the time. I'm not a big fan of the big glass tubes. They promptly fixed the issue without any delays or drama. It took me a few days slowly turning the dial up to finally get it where I wanted. I noticed my old hygger heater beginning to fail and my wife ordered this one. Sometimes it gets outside of it's ability to cool but only within a few degrees.

"The seller was wonderful."

The heater is super thin and the reflective surface is interesting. The design is sleek and modern looking. Ick for instance detaches from fish at 86 degrees and dies at 89. This is a powerful heater that holds temperature very well. We wish the controls were available in Farenheit also to make things a little easier. Just be careful and keep an eye on your temp settings when you have kids over! So far I like it setup was super easy.
