This is a powerful heater that holds temperature very well.
Compared to my marina 100w heater in the photo, it does look rather bulky, but it blends in just fine in my cichlid tank.
When I first plugged in the heater, my current temp readout was at 76f and I set it to 80f.
It took about an hour to reach 80f, which is fairly quick. My marina heater takes a few hours.
The temperature has been holding all day, even in a colder room. My room temp at the moment is 70f, with the window slightly cracked open and the tank is about 3 feet from the window. It kicks in when it’s 1 degree lower, which is more ideal for those with sensitive livestock. Some heaters don’t kick in until the temp is down to 5f lower than your desired setting! You don’t have to worry about wide temperature swings with this unit.
I appreciate the exterior temp readout and control module. It comes with a hanging kit and can be secured on the edge of the tank. It does take a few presses to get to your desired setting, because there’s only one button. It just cycles through to 93f and starts over. Pressing and holding the button for 5 seconds changes it from F to C readouts.
The suction cups are very good quality and didn’t give me any trouble, but time will tell.
Another thing I appreciate is that it has a memory setting in case the power goes out. I tested it by unplugging and replugging it. The setting always stayed the same. This gives me peace of mind.
The only thing I do not like about the exterior module is that it can be easily accessed by kids… and kids love pushing all sorts of buttons… But I am single and don’t have to worry about this.. Just be careful and keep an eye on your temp settings when you have kids over! Or better yet, conceal it to the back corner.
It does blend well in some setups and may look bulky in others. This is something to consider.
Personally for me the housing doesn’t bother me. I’m not a big fan of the big glass tubes.
My yellow lab cichlids are too big to fit in the slots, so I don’t have to worry about any misadventure.
I will keep testing this throughout the upcoming season and will update on any changes.

This is a good heater if you have a big aquarium. I love the controls that hang on the outside of the aquarium, and that it tells you how warm the water at that spot actually is. I had mine at the opposite end of the tank from the heater, and it made me aware of the fact that I needed a powerhead to circulate the water in my tank.

UPDATE: (glass cracked when heater was taken out of tank seasonally – )HOWEVER- seller reasonably requested photos of the damaged item which I provided and a new replacement heater was received the next day or so – EXCELLENT customer service!!

I bought this for use when making salt water in a 40-gallon trash can. It works great! I have a RO/DI system in the house which takes a couple hours to fill the can. I plug this in as soon as the water submerges the heater. It does an excellent job of heating the water as the can fills. The water is always heated to 77 degrees by the time I mix in the salt and am ready for the water change. I love it!
