Terrible Heater! By Damian on 3/6/2014
Damian wouldn't recommend this product to a friend
Have had this heater running less then a year and the temperature probe just fell apart where the wire goes into it giving a false high reading on the controller. Cheap construction. Would not recommend this for any tank.
Find another heater By reefer on 12/20/2013

Do not buy this product. All of the negative reviews. You should be prepared for. I do want to say a good thing however. Its a really neat set up. I was really excited about it at first. I was so happy to have a heater with a separate controller to AVOID OVER HEATING. NO! First of all. I was ok with the 2°constant swings because the features gave me a piece of mind. My 1000watt heater got stuck in the on position. And the digital controller said it was turned off. Nope. Luckily I have an apex tank controller and it shut the pos off after a 3° climb saving my expensive reef! Now my $500 controller is turning the heater on and off. Im about to put a $60 petsmart heater in its place because I don't trust it to continue heating. To make things worse I cant get ahold of jbj. They wont return my calls or emails.

What a hassel! By dajesso on 4/11/2013
dajesso wouldn't recommend this product to a friend
I bought this kit. The heater indicator light did come on to indicate heating. JBJ sent me a replacement controller. This one did not work either. They sent me three of these where the heat indicator light did not come on. Finally they sent me one and the power did not even come on. So I sent this one back. They finally sent one that worked in full. The forth or fifth one they sent worked. I lost count. One thing for sure they stand behind the product but how they can send so many that did not work is beyond me.
Terrible product, lasts just past warranty then breaks 3X! By CompletelyHonest on 1/9/2013
CompletelyHonest wouldn't recommend this product to a friend
I have owned 3 1000 watt titanium JBJ (Just Buy Junk) heaters and all have quit working right at the end of the warranty period. Both times the extreme temperature drop wiped out my 120 gallon SPS tank with some very expensive rare acro colonies. I wouldn't recommend these to anyone. The controller seems to last but the heating unit is JBJunk. Overpriced for a pretty package, instead they should have spent the extra money on R&D or better manufacturing.
Must be replaced yearly By Carlo on 11/11/2012
Carlo wouldn't recommend this product to a friend
This heater breaks every year either the heating element gives out or the digital display. Company (JBJ) does not stand behind the product once they replace it. I know its tempting to buy but trust me, its unreliable. I baby my equipment too.
Does NOT last By Carlo on 11/8/2012
Carlo wouldn't recommend this product to a friend
Great product for one year. Breaks once a year. The company will replace it while under warranty without any questions asked but after that replacement they are useless. First time mine broke heating element stopped working, one year later the digital display stopped. Would NOT buy again. Customer service was rude after asking for another replacement or even a discounted price for multiple purchases.
So far so good By Jeremy on 10/24/2012

I have the 800w heater on my 225g tank for 8 months and have had no problems so far. Keeps my tank within +-2 degrees. Only reason I am giving 4 stars is for the price.
I love this product By Ehsan on 9/21/2012
Ehsan would recommend this product to a friend
i think that to all who did leave a bad feed back that they need to go and do some research because this heater needs to be calibrated and if you don't do that you will not get an correct tempter. this product is one of a kind and i love it

Ive got 4 of these in operation, and three of them have failed in one way or another in the past year. Save your money DO NOT BUY THIS.
Heater is unreliable in the long term. By Tom on 7/18/2012
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 7/8/2012
mudgenfs wouldn't recommend this product to a friend
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 6/26/2012
Philip wouldn't recommend this product to a friend
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!
FAIL By chad on 6/22/2012

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 1/12/2012
woodapple wouldn't recommend this product to a friend
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.....

Good product, room for improvement By Bud on 8/17/2011
Bud would recommend this product to a friend
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.
