"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.

"Temperature!"

Personally for me the housing doesn't bother me. It took me only two tries to get it to the correct temperature. Easy enough to let it run all the time. I left seller feedback yesterday but have yet to hear from the seller. Come on Fluval, expect better from you. This heater is NOT fully submersible. I had a thermometer on opposite side of tank and the heater was dead on true.

"I do recommend."

I got a hold of Amazon, who put me in touch with the seller. The controller is easy to use, very accurate and reliable. I got this heater for my 55 gallon aquarium. And kids love pushing all sorts of buttons. And I get to keep the first one I bought! I bought a similar one at the pet store and it barely worked. The design is sleek and modern looking.

"5 degrees."

The temperature difference was very minor. I hope these suction cups work very well. I am very happy with this purchase. --The heater itself is a bit shorter if your tank is a short one. Seems to keep the temp n the tank fairly regular. It took me a few days slowly turning the dial up to finally get it where I wanted. We received the chiller promptly and put it into use.

There is no protection from it banging on the glass tank. There is a misconception on the internet that the heater isn't fully submersible. --The cylinder or rod diameter is bigger. They shipped us the upgraded version that also heats! All seem to vary between 1-2 degrees of each other which doesn't concern me much. I like to keep it at 72 and from my thermometer it is reading at exactly 72. There is no protection from it banging on the glass tank.

The heater protector was very heavy plastic and slim lined which is great. Per my thermometers, they are all staying constant. If the water runs low or air gets in the heater shuts off. This heater works, but the dial it isn't very accurate. My fish likes to get close to it and he has never been hurt by it. They shipped us the upgraded version that also heats!
