5.0 out of 5 stars Great Reef Heater, April 1, 2010

Heater works great for my Reef setup. Placed in my sump and keeps temperatures constant at my desired temp. Never fluctuates. Interesting controller with the LED, easy to use and operate. Gives the tank a higher tech look. I have their HMA series on the way for my small nano. Will review that when it comes in. Strongly recommends Finnex's titanium heater line.

This heater is Terrible! I don't even want to give it one start but you cant give it negative stars.

I bought 2 of these. 1 for my 46 gallon tank and one for my 72.

In both cases the electronics where you change the temperature malfunctioned.

In one case it was not dangerous. The first case it just stopped showing the temperature. I could not tell if it was working since there is no light on the heater itself the only way I could tell if the heater was working was the press the up or down button and wait and see if my temperature went up or down. I did not want to Cook or Freeze my fish so I tossed that one out.

Yesterday the 2nd one malfunctioned and it could have been bad if I had not been at home.

I was in the kitchen cooking when I head a loud POP then a hiss from the fish tank. As I got closer to the tank I got a faint smell of smoke. Further investigation lead me to the heater and once again the plastic device used to turn the temperature up or down. The numbers burnt out again but this time it was very hot. I unplugged it. When I put it to my nose I could smell burnt electronics.

I originally wanted to buy the JBJ true temp 300W but I cheeped out. I will not make the same mistake twice!

3.0 out of 5 stars not perfect, but nothing is either, December 2, 2010

purchased two 300W for a 150g reef tank. Had a pair of Marineland Steath heater in there for two years and it blew apart. One of the 300W HMO works fine, the second one would not heat up. Open the control box and found one of the leg of the SCR not solder on the board. Re-solder and it is working OK now. Seem like no QC took place.
