2 Weeks in to its us I start getting shocks disconnect one by one my pumps , heaters and i found the root cause this heater , I wonder if that's the 1st step before it explodes in your aquarium . Sending a complain to the attorney general in my state since from what I read in reviews this heaters are a hazard to human life.

I have now had this heater for a year in my 29 gallon Nano. The temperature has NEVER deviated from the setting. Need I say more? I am very pleased.
I Should Have Known. Do Not Buy! By Keisha Kornbread on 5/13/2015

I read the threads regarding the 200w heaters exploding but I didn't think it would happen to me. And this morning it did. I heard a pop while I was getting ready for work this morning and standing next to the tank. I looked into the cabinent and a puff of thick white smoke rising from the sump. I ran to my macbook and shut all flow off because I knew what was happening. On the way to the computer I heard another pop. When I moved the cabinent walls off of the stand the smell hit me. I pulled the heater out and it had exploded with 2 long slits the length of the heater. That black stuff that I read oozes out of the heater had started to leak into the tank but was contained in one chamber of the sump. I quickely dismantled the sump and removed two fish I was holding in the fuge chamber. They were close to dieing but I managed to save them. The foul water hadn't made it's way into the DT because I knew exactly what h ad happened and I ran to the computer. Had I not been home everything would have been dead in there. The thick grease that is contained in these heaters is almost impossible to clean up and it took alot of papertowels and arm-power to get most of it out of the sump. I was late to work several hours but the tank seems to be fine. I should have pulled this heater out last year when I read the Exploding Cobalt Heater threads online. I will never use another one of these. My eheims have been rock solid and I will only use those going forward.
Stopped Working By Aron on 4/25/2015

Heater stopped working after about a year, luckily the apex alarm went off as the temperature was falling and allowed me to put in a backup heater to save everything. When it was working properly it was a nice heater...not sure if the 200W was true because didn't perform like my other 200W heaters.
Great! By Tony on 4/11/2015

I started out buying a 75watt (from a different store), and keeping the setting at 78 degrees in my sump, water stays at 77.4-77.8.
I have recently ordered a 150w from BRS for in my display tank. My experience with the 75w i would expect nothing less then a great product from the 150w.
Waiting on quality control. By Turf on 4/9/2015

Used this heater for just over a year. I love the concept but the heater stopped working right after the warranty went out - bought in late 2013. If I found out that they had improved the component quality I'd buy one again.
Amazing for nano tank By Mike on 3/29/2015

I have this on my bio cube and it fits perfectly in the back chamber the low-profile give me great room for filter media. I've had it running continuously for around eight months now with zero issues been able to keep constant temperature of 78 which I've checked with secondary thermometers on my apex unit
Malfunctioned after a month....May have had a lemon. By Chris on 3/27/2015

I had the 75w for a 20 gal frag tank. Kept it set at 80 deg which kept the tank around 78.5 deg for about a month. Came home one night to find my acros in serious distress. Tank temp was 70 deg. There had not been a power outage. Heater was still set at 80 deg. Put the acros in my DT. Unplugged and plugged the heater in and reset it to 80 deg. Water came up to about 79 degrees that night. Came home the next night and the tank temp was 72 deg. I won't use this heater any more.
Avoid By Paul on 3/23/2015

Nothing here warrants the price of these heaters. The shape is convenient for a sump. They are reasonably accurate. I have owner three and none have lasted more than 24 months. Each has gone with an audible pop and the acrid smell of burning insulation. One of the three tripped the GFCI. None were kept full submersed.
Good but expensive and weak By Patrick of Bay Area Coral on 3/16/2015

I purchased the 150W on NOVEMBER 22, 2014 and have been using it since. I sleek design and digital temperature sensor is great, but it was not enough to keep my 50 gallon aquarium warm during winter. I had to supplement with another 150w heater. I am looking forward to the new line of 300w+ dual heaters!
Fried my corals By Chris on 2/9/2015

This heater worked great for the first six months or so but then I came downstairs one morning to find my anemones, corals, and clam in obvious distress. Put my hand in the water and got a serious shock. The bottom seam of this heater had split and was electrifying my livestock. Managed to save about half of them, but will stay far away from these in the future.
Blew up! By Flannigan on 2/8/2015

I had the 200 watt heater and thought it was great for the first six months of use, until it blew up in my sump. Five minutes after I got home from work, I heard a loud band, like a firecracker. I wasn't sure what it was until I noticed my dogs smelling the fish tank stand. I walked over to the tank and started smelling a very bad burning plastic/electrical smell. By the time I got to the tank, so much smoke was around it. I opened up the cabinet to see the the heater had blown up and was bubbling smoke into the water. I quickly unplugged the heater and opened all my windows and doors. There was so much smoke, I could barely see anything in the cabinet. On top of that, the heater released a gooey black tar like substance into the tank that was next to impossible to clean up. If i wasn't home, my whole house would have filled up with toxic smoke and possibly made my dogs sick or something. This was my experience and have noticed from internet searches that I'm not alone. Think twice before getting one of these.
