"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.

"Buy with confidence!"

Those turned out to be a hit and miss. When i installed them, i let them sit in the tanks without power for 6-24 hours. --The heater itself is a bit shorter if your tank is a short one. I bought a similar one at the pet store and it barely worked. But my guys don't read them and don't listen! I am very happy with this purchase. So when I first received it it didn't work and I was very disappointed.

"I like this heater."

The heater is super thin and the reflective surface is interesting. Also were nice along the whole process. I used to try those other cheap heaters sold on amazon. The controller is easy to use, very accurate and reliable. The cover over the heating tubes is great, the turtles claws can't damage the tube. Product was received fast, works excellent! I adjusted the set temperature a little lower to be more in the range I wanted.

"Quality was amazing."

I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. Or better yet, conceal it to the back corner. I used to try those other cheap heaters sold on amazon. I went ahead and went with the the larger 300W for my 45 gallon. The line is there due to regulations in certain countries. Sometimes it gets outside of it's ability to cool but only within a few degrees. Sometimes it gets outside of it's ability to cool but only within a few degrees.

"I angled it."

My heater is fully submerged underwater and works perfectly fine. They promptly fixed the issue without any delays or drama. But I am single and don't have to worry about this. This is only day one though, so I shall keep an eye one it. Come on Fluval, expect better from you. I was amazed how quickly I got to my temperature I need it 78 degrees. There is no protection from it banging on the glass tank.

"No copper lines!"

Pressing and holding the button for 5 seconds changes it from F to C readouts. This heater works, but the dial it isn't very accurate. Just be careful and keep an eye on your temp settings when you have kids over! I love the heater otherwise, but I'm afraid some water has gotten inside the heater. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. Also were nice along the whole process. I'm in the process of setting up for tanks.

"I have a betta in a 1."

Keeps the temperature within 1 degree of what you set it to at all times. The cover over the heating tubes is great, the turtles claws can't damage the tube. I will be ordering more of these in the future. I will be ordering more of these in the future. Now, both points are clear on the package instructions.

"Impressive."

I would definitely recommend this product. And I get to keep the first one I bought! It would stick out of my 30 g wide tank if I were to put it vertical. What more could you ask for great job Hygger Duncan. I waited a little bit to write the review so it could be accurate. Will update my review if any changes occur. I recieved this product without the instructions or the added thermometer.

"Not very reasonable."

I like the fact that it comes with a digital thermometer. 210 gallon ones and one 90 gallon bow front tank. What more could you ask for great job Hygger Duncan. This heater warmed it right up and now my Betta and guppies are more active. The temperature lights up so it's very easy to read. Maintains it well except when the weather is already warm then it over heats it. The bonus digital thermometer it came with has been super helpful, and is accurate.
