"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.

"Highly recommended."The temperature lights up so it's very easy to read. The heater is super thin and the reflective surface is interesting. Was very impressed with the quality of this heater. The line is there due to regulations in certain countries. They shipped us the upgraded version that also heats! I use this little heater for my 10 gallon quarantine tank. I used to try those other cheap heaters sold on amazon.

ViaAqua VA 300Q Final Thoughts
"Great concept."It took about an hour to reach 80f, which is fairly quick. Those turned out to be a hit and miss. If the blue light is flashing it means the heater is not fully submersible. 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 think it works well to not stand out like other heaters.

hygger HG-925 Final Thoughts
"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.

"I like this heater."I noticed my old hygger heater beginning to fail and my wife ordered this one. The heater is super thin and the reflective surface is interesting. After several weeks of running the heater. Come on Fluval, expect better from you. Takes a little while to drop the temps if it is hot in the garage. We wish the controls were available in Farenheit also to make things a little easier. The heater is being used in a 40 gallon breeder.
