Heater is unreliable in the long term. By Tom on 7/18/12
Tom wouldn't recommend this product to a friend
The cost of the unit implies it is of high quality when it is not. After about six months the Indicated temperature diverged from the actual by more than ten degrees and the unit could not be recalibrated. Luckily it was not heating season. The unit should not be trusted on a reef with any significant investment. Save your money and put it towards a controller of better quality.
controller failed 3 times, heater melted down in tank By mudgenfs on 7/8/12

Had problems from the start. Got home tonight and smelled electrical burning. Ran downstairs and in my sump the heater was smoking, bubbling the water, and glowing bright red. I could see the heater body distorting. It really scared me but honestly I'm not surprised because the controller it came with has failed 3 times since December
Failed heater By Philip on 6/26/12

The heater worked for about 6 months then failed with the same symptoms as some of the other unfavorable reviews. The readout shows 88.9 degrees even though the actual temperature is about 75 degrees. The calibration feature no longer works. I wish that I had read through these reviews before I made this purchase!

6 months into use, thermometer probe failed. Terribly common problem searching forums. Digital readout was 15 degrees off from actual temp.....JBJ no help at all. Will never buy another of their products, complete jerks about answering questions.
worst experience in 7 years of the hobby.

Just received a 500 watt and contrary to the advertisement and photos on this site, the heater and probe mounts are suction cups. I feel lied to and ripped off. Waiting for a response to resolve with BRS

After running two 300 watt unit for a year both have failed. Sent an email to JBJ to see what they have to say. Both unit show temp 87 but the water was in the low 70's. Save you tank and do not buy this heater. Changed the parts around same issue.
SAVE YOUR TANK and DO NOT BUY THIS.

Love that this heater has a temperature probe that you can locate 5 feet from the heater for a more accurate reading of your tanks temperature.
1 out of three heaters fail By woodapple on 1/12/12

I have three of the heaters and the one on the main display is the one that fails of course. I do not have a system that will alarm if teh temp fails so I was putting too much faith in the unit. Recommend you get a contorler with an alarm. It did work for 1 year.... Now I am getting DA reef keeper.....

Ive been running this unit for over 6 months and have had no problems with it. Overall for me its been a reliable affordable unit.
Good product, room for improvement By Bud on 8/17/11

Great product, works well, vast improvement over glass heaters with suction cups with totally suck.
Some things I would have improved on: The sleeve tends to trap waste. Not much way around this. Also I think I'm going to break the thing whenever I try to take it apart, snaps together weird, and if you slide it off the rubber cap on the end of the heater pops off (not siliconed on well) but doesn't affect function. I also wish it had an adjustable range setting instead of +/- 1F. Yeah it doesn't cycle on and off a lot, but I would prefer to see a tighter range option. It's just programming, I don't know why they didn't do that.
Great Aquarium Heater By Shannon on 8/4/11

These heaters are reliable and built to last. I have yet to have a problem with the design. While they are pricy they are well worth it in the long run. Can't tell you how many others I've been through.
