"Problem solved."

Now, both points are clear on the package instructions. We would consider a replacement and then we would return the defective unit. My fish likes to get close to it and he has never been hurt by it. 210 gallon ones and one 90 gallon bow front tank. I'm in the process of setting up for tanks. It is safe and dependable and comes with a one year warranty. It's pretty noticeable, but I don't really care.

"Looks as advertised."

So far I like it setup was super easy. This is only day one though, so I shall keep an eye one it. The temperatures are pretty accurate. When i installed them, i let them sit in the tanks without power for 6-24 hours. Very easy to install and the adjustable temperature gauge is pretty accurate. The temperature difference was very minor. Seems to keep the temp n the tank fairly regular.

"Very pleased so far."

So when I first received it it didn't work and I was very disappointed. I was amazed how quickly I got to my temperature I need it 78 degrees. The suction cups are large, high quality and seem to stick great. I wouldn't buy any other heater, unless one of these stops working. It took about an hour to reach 80f, which is fairly quick. I got this heater for my 55 gallon aquarium. I have 3 of the Fluval heaters, in various sizes.

When overheating (more than 93 Fahrenheit), it will automatically shut down, and it will automatically reset when it cools to the starting temperature (usually two degrees lower than the set temperature).

"They contacted me."

This does a great job at regulating the temp in my 10 gallon. I like the fact that it comes with a digital thermometer. This heater works, but the dial it isn't very accurate. I wouldn't buy any other heater, unless one of these stops working. I have only had minor problems with the suction cups. I like how the heater is constructed. Beware, but we are hoping for a good outcome!

"Can be hidden."

Sometimes you may have to tinker around with the dial. There is a misconception on the internet that the heater isn't fully submersible. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. Or better yet, conceal it to the back corner. This this is amazing and is worth the money. I contacted the manufacturer and they sent me a new unit in less than a week! Or better yet, conceal it to the back corner.

"5 or even."

All seem to vary between 1-2 degrees of each other which doesn't concern me much. The bonus digital thermometer it came with has been super helpful, and is accurate. For Discus you need warm and accurate heater and this seems to do the trick. There is a misconception on the internet that the heater isn't fully submersible. If the water runs low or air gets in the heater shuts off. And kids love pushing all sorts of buttons. Personally for me the housing doesn't bother me.

"Pricing was good."

This has the best controller that I have found on the market. The temperature lights up so it's very easy to read. I have a 10gallon tank that was at 72 degrees. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. Checked the accuracy of the heater with an infrared thermometer.

"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.
