"Best addition to my tank."

There is no protection from it banging on the glass tank. Sometimes you may have to tinker around with the dial. I got this heater for my 55 gallon aquarium. Awesome chiller, perfect for Hydroponics. The heater is easy; turn the dial to set temp and plug in. 210 gallon ones and one 90 gallon bow front tank. I got the 200W variant for my 54 gallon corner tank that's housing goldfish.

"Great concept."

Keeps the temperature within 1 degree of what you set it to at all times. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. The temperature has been holding all day, even in a colder room. I think it works well to not stand out like other heaters. It is a bonus that the heater is titanium. Once I opened the box i noticed the quality of the construction. I have it set to 81F to get a 77F water temp.

"The accuracy is perfect."

This product came in the nick of time! I got this heater for my 55 gallon aquarium. They promptly fixed the issue without any delays or drama. When i installed them, i let them sit in the tanks without power for 6-24 hours. I adjusted the set temperature a little lower to be more in the range I wanted. Those turned out to be a hit and miss. I think it works well to not stand out like other heaters.

"5 stars in my book!"

--Temperature adjustment labeling is on top rather than on the rod. What more could you ask for great job Hygger Duncan. --The heater itself is a bit shorter if your tank is a short one. The setting always stayed the same. So when I first received it it didn't work and I was very disappointed. Was very impressed with the quality of this heater. No biggie, but annoying nonetheless.

Now, both points are clear on the package instructions. I use this little heater for my 10 gallon quarantine tank. The temperature difference was very minor.
