"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.

"So far so good!"

But I am single and don't have to worry about this. The temperatures are pretty accurate. The red light means it's off, blue light means the temperature is constant. I was worried about the quality but I am thoroughly impressed with this heater! When i installed them, i let them sit in the tanks without power for 6-24 hours. This has been in my fish tank for a few months now and it's been absolutely perfect! I use a 50 for a 5 gal and a 10 gal tank.

"Just perfect for my 1."

I'm in the process of setting up for tanks. This little heater is perfect; this is our third purchase of the same heater. This heater warmed it right up and now my Betta and guppies are more active. I like to keep it at 72 and from my thermometer it is reading at exactly 72. Product was received fast, works excellent! Those turned out to be a hit and miss. It would stick out of my 30 g wide tank if I were to put it vertical.

"16-26 gallons 75 watt 10."

Keeps the temperature within 1 degree of what you set it to at all times. It's pretty noticeable, but I don't really care. I bought a similar one at the pet store and it barely worked. This is a great heater that is very easy to set up and program. And kids love pushing all sorts of buttons. 210 gallon ones and one 90 gallon bow front tank. Checked the accuracy of the heater with an infrared thermometer.

"Pricing was good."

This has the best controller that I have found on the market. The temperature lights up so it's very easy to read. I have a 10gallon tank that was at 72 degrees. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. Checked the accuracy of the heater with an infrared thermometer. Now, both points are clear on the package instructions. This little heater is perfect; this is our third purchase of the same heater.

"This is a quality heater."

I have 3 of the Fluval heaters, in various sizes. It's pretty noticeable, but I don't really care. We received the chiller promptly and put it into use.

"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!

"I like this heater."

I am very happy with this purchase. It's pretty noticeable, but I don't really care. I'm not a big fan of the big glass tubes. Thanks for the great customer service! Once I opened the box i noticed the quality of the construction. The temperature gauge is fairly accurate in my 55 gallon tank. This has the best controller that I have found on the market.

"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.
