"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.

"Love this heater!"

My marina heater takes a few hours. They shipped us the upgraded version that also heats! And I get to keep the first one I bought! Takes a little while to drop the temps if it is hot in the garage. The heater is super thin and the reflective surface is interesting. I am very happy with this purchase. I like the fact that it comes with a digital thermometer.

"I'll see with these."

Well worth the money the first one I bought still works great. Maintains it well except when the weather is already warm then it over heats it. I tested it by unplugging and replugging it. I have it set to 81F to get a 77F water temp. This heater is NOT fully submersible. Sometimes you may have to tinker around with the dial. The heater is super thin and the reflective surface is interesting.

"And I am glad I did."

--The cylinder or rod diameter is bigger. It's pretty noticeable, but I don't really care. This is only day one though, so I shall keep an eye one it. I wouldn't buy any other heater, unless one of these stops working. The heater is being used in a 40 gallon breeder. I emailed the email it says to and told them. I used to try those other cheap heaters sold on amazon.

I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I have only had minor problems with the suction cups. I have a 10gallon tank that was at 72 degrees.

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.

The red light means it's off, blue light means the temperature is constant. It does blend well in some setups and may look bulky in others. 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. This heater works, but the dial it isn't very accurate. My heater is fully submerged underwater and works perfectly fine.
