"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.

"One word of caution."

You don't have to worry about wide temperature swings with this unit. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. But I am single and don't have to worry about this. It is a bonus that the heater is titanium. I have 3 of the Fluval heaters, in various sizes. This heater is NOT fully submersible. I would definitely recommend this product.

"Easy to unpack."

I used to try those other cheap heaters sold on amazon. Pressing and holding the button for 5 seconds changes it from F to C readouts. Once attached to the tank wall I've had no issues with it coming off. We received the chiller promptly and put it into use. For Discus you need warm and accurate heater and this seems to do the trick. I like the fact that it comes with a digital thermometer. Takes a little while to drop the temps if it is hot in the garage.

I use a 50 for a 5 gal and a 10 gal tank. Was very impressed with the quality of this heater. It is a bonus that the heater is titanium. This heater is NOT fully submersible. Product was received fast, works excellent! Personally for me the housing doesn't bother me. I got the 200W variant for my 54 gallon corner tank that's housing goldfish.

"Excellent build quality."

Come on Fluval, expect better from you. I have only had minor problems with the suction cups. The bonus digital thermometer it came with has been super helpful, and is accurate. This is a great heater that is very easy to set up and program. All seem to vary between 1-2 degrees of each other which doesn't concern me much. But my guys don't read them and don't listen! Two inches above that is a waterline for maximum.

"I bought the 7."

The red light means it's off, blue light means the temperature is constant. --The cylinder or rod diameter is bigger. I think it works well to not stand out like other heaters. This heater is NOT fully submersible. This this is amazing and is worth the money. Sometimes you may have to tinker around with the dial. For Discus you need warm and accurate heater and this seems to do the trick.

"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.

"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.

"Highly recommended."

It's only been set up for a month we'll see how well it does in a few months. This does a great job at regulating the temp in my 10 gallon. Seems to keep the temp n the tank fairly regular. But my guys don't read them and don't listen! I'm not a big fan of the big glass tubes. --Temperature adjustment labeling is on top rather than on the rod. Easy enough to let it run all the time.
