"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.

The temperatures are pretty accurate. I noticed my old hygger heater beginning to fail and my wife ordered this one. I left seller feedback yesterday but have yet to hear from the seller. I will definitely be buying another one for my other tanks at bigger one. But my guys don't read them and don't listen! The suction cups are large, high quality and seem to stick great.

"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!

"Great product!"

I use a 50 for a 5 gal and a 10 gal tank. It took about an hour to reach 80f, which is fairly quick. 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. I wouldn't buy any other heater, unless one of these stops working. It took me a few days slowly turning the dial up to finally get it where I wanted. I recieved this product without the instructions or the added thermometer.
