"Looks as advertised."

It is a bonus that the heater is titanium. All seem to vary between 1-2 degrees of each other which doesn't concern me much. This has the best controller that I have found on the market. Sometimes it gets outside of it's ability to cool but only within a few degrees. The suction cups are large, high quality and seem to stick great. But I am single and don't have to worry about this. Was very impressed with the quality of this heater.

"Bought the 300W one."

Am a totally sold customer and would recommend them to anybody! All seem to vary between 1-2 degrees of each other which doesn't concern me much. The temperature has been holding all day, even in a colder room. It took me only two tries to get it to the correct temperature. I have only had minor problems with the suction cups. --The heater itself is a bit shorter if your tank is a short one. Bought it as a chiller for the k40 CO2 laser.

"This heater works great."

I have 3 of the Fluval heaters, in various sizes. If the water runs low or air gets in the heater shuts off. It took about an hour to reach 80f, which is fairly quick. You don't have to worry about wide temperature swings with this unit. I wouldn't buy any other heater, unless one of these stops working. So far I like it setup was super easy. Well worth the money the first one I bought still works great.

"Bought the 300W one."

Per my thermometers, they are all staying constant. I will be ordering more of these in the future. My marina heater takes a few hours. All seem to vary between 1-2 degrees of each other which doesn't concern me much. The suction cups are large, high quality and seem to stick great. Once attached to the tank wall I've had no issues with it coming off. This is only day one though, so I shall keep an eye one it.

"I like this heater."

The temperatures are pretty accurate. The suction cups are large, high quality and seem to stick great. This is only day one though, so I shall keep an eye one it. It would stick out of my 30 g wide tank if I were to put it vertical. I got this heater for my 55 gallon aquarium. Well I bought a second one took me only one trying to get the right temperature. The cover over the heating tubes is great, the turtles claws can't damage the tube.

"Peace out."

I would definitely recommend this product. The temperatures are pretty accurate. If the blue light is flashing it means the heater is not fully submersible. Sometimes it gets outside of it's ability to cool but only within a few degrees. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I dont know, and havent tried just yet. It does blend well in some setups and may look bulky in others.

"Will not switch!"

I have a 10gallon tank that was at 72 degrees. It took me a few days slowly turning the dial up to finally get it where I wanted. The suction cups are large, high quality and seem to stick great. The design is sleek and modern looking. I like to keep it at 72 and from my thermometer it is reading at exactly 72. After several weeks of running the heater. I used to try those other cheap heaters sold on amazon.

"6 gallon tank."

I had a thermometer on opposite side of tank and the heater was dead on true. The bonus digital thermometer it came with has been super helpful, and is accurate. Sometimes it gets outside of it's ability to cool but only within a few degrees. They shipped us the upgraded version that also heats! I love the heater otherwise, but I'm afraid some water has gotten inside the heater. For Discus you need warm and accurate heater and this seems to do the trick. Those turned out to be a hit and miss.
