"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.

The cover over the heating tubes is great, the turtles claws can't damage the tube.

"Seems very well built."This heater is NOT fully submersible. It took me a few days slowly turning the dial up to finally get it where I wanted. Keeps the water consistent and it's easy to adjust! And kids love pushing all sorts of buttons. Will update my review if any changes occur. No biggie, but annoying nonetheless. It's only been set up for a month we'll see how well it does in a few months.

"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.

"Just bought a second one!"So if you set it to 78 degrees, the heater will not kick on until it reads 76. This this is amazing and is worth the money. They shipped us the upgraded version that also heats! The temperature has been holding all day, even in a colder room. I think it works well to not stand out like other heaters. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. I was worried about the quality but I am thoroughly impressed with this heater!
