"Bought the 300W one."

Personally for me the housing doesn't bother me. I used to try those other cheap heaters sold on amazon. Sometimes it gets outside of it's ability to cool but only within a few degrees. There is a misconception on the internet that the heater isn't fully submersible. Easy enough to let it run all the time. I noticed my old hygger heater beginning to fail and my wife ordered this one. This heater warmed it right up and now my Betta and guppies are more active.

"So far it seems great!"

I tested it by unplugging and replugging it. The red light means it's off, blue light means the temperature is constant. The heater is easy; turn the dial to set temp and plug in. It's pretty noticeable, but I don't really care. The temperature gauge is fairly accurate in my 55 gallon tank. This this is amazing and is worth the money. After several weeks of running the heater.

Come on Fluval, expect better from you. We wish the controls were available in Farenheit also to make things a little easier. Easy to read the temp and know exactly how warm the water is. There is no protection from it banging on the glass tank. I was worried about the quality but I am thoroughly impressed with this heater! The temperature has been holding all day, even in a colder room. This is a powerful heater that holds temperature very well.

"No worries, though."

The bonus digital thermometer it came with has been super helpful, and is accurate. You program it for temperature you want your tank to be. Well I bought a second one took me only one trying to get the right temperature. Sometimes you may have to tinker around with the dial. The heater protector was very heavy plastic and slim lined which is great. So if you set it to 78 degrees, the heater will not kick on until it reads 76. I left seller feedback yesterday but have yet to hear from the seller.

"One word of caution."

So if you set it to 78 degrees, the heater will not kick on until it reads 76. I confirm it with my cooking digital probe thermometer. I recieved this product without the instructions or the added thermometer. The line is there due to regulations in certain countries. This heater warmed it right up and now my Betta and guppies are more active. But my guys don't read them and don't listen! So far I like it setup was super easy.

I wouldn't buy any other heater, unless one of these stops working. Easy enough to let it run all the time. I'm not a big fan of the big glass tubes. They promptly fixed the issue without any delays or drama. It took me a few days slowly turning the dial up to finally get it where I wanted. I noticed my old hygger heater beginning to fail and my wife ordered this one. Sometimes it gets outside of it's ability to cool but only within a few degrees.

"The seller was wonderful."

The heater is super thin and the reflective surface is interesting. The design is sleek and modern looking. Ick for instance detaches from fish at 86 degrees and dies at 89. This is a powerful heater that holds temperature very well. We wish the controls were available in Farenheit also to make things a little easier. Just be careful and keep an eye on your temp settings when you have kids over! So far I like it setup was super easy.

What more could you ask for great job Hygger Duncan. Very easy to install and the adjustable temperature gauge is pretty accurate.

"Quality was amazing."

And I get to keep the first one I bought! We would consider a replacement and then we would return the defective unit. Also I like how it shows both the current temperature and the set temperature. Per my thermometers, they are all staying constant. This is only day one though, so I shall keep an eye one it. I contacted the manufacturer and they sent me a new unit in less than a week! My fish likes to get close to it and he has never been hurt by it.

"7L Imagitarium tank."

This product came in the nick of time! Bought it as a chiller for the k40 CO2 laser. If the blue light is flashing it means the heater is not fully submersible. If the water runs low or air gets in the heater shuts off. --The cylinder or rod diameter is bigger. I think it works well to not stand out like other heaters. You don't have to worry about wide temperature swings with this unit.

There is a misconception on the internet that the heater isn't fully submersible. Come on Fluval, expect better from you. The controller is easy to use, very accurate and reliable. --Temperature adjustment labeling is on top rather than on the rod. I use a 50 for a 5 gal and a 10 gal tank. Two inches above that is a waterline for maximum. Temperature is slightly off by running a little warmer.

"Problem solved."

The heater is easy; turn the dial to set temp and plug in. The design is sleek and modern looking. It took about an hour to reach 80f, which is fairly quick. This is a great heater that is very easy to set up and program. The setting always stayed the same. It just cycles through to 93f and starts over. At this time I highly recommend this product.
