Started out great.... By Adam on 4/15/2016

So like everyone else I loved this heater for it's sleek design and ease of use. I bought my heater as a reef package with my aquarium back in May of 2014 and it's worked like a champ. Well it worked well until last week when it tried to cook my entire system. I caught it early enough that the heater didn't melt like some other people have stated. My aquarium was heated up to 92 degrees when i caught the issue and did lose some livestock. Since the issue was caught before it got well out of hand, I was able to save most of the fish and coral.
Well, all heaters will fail at some point so it would be a good idea to invest in a external controller as a safeguard. For the price I would of expected it to work longer and not fail in the ON position. Just expected more from this brand.
Problem heater By sailfin777 on 3/11/2016

many people that I know in the hobby say that the heater is prone to cracking and causing a fire. They'd have switched to the eheim model heater which are cheaper. I have removed all my cobalt heaters and replaced them with the eheim models.
Unreliable By Bret on 3/1/2016

I have owned 5 of them in the past few years. Three of the five have burnt up and smoked out my fish room with the smell of melting plastic. Just not reliable.

the fact that i can get this in my ac70 refugium and not in my display makes it worth it plus haven't had any issues with it

Terrible heater By Snupa on 11/8/2015

This heater like many others stated exploded in my tank and sent off a a large plume of smoke across the room that had a terrible smell. I should have known better since so many others are talking about this on other forums. I'm disappointed in cobalt that there has been no real acknowledgement of the issue. Beware! If you have especially the 200W swap it out now!
Dangerous and a BRS embarassment By Brendan on 10/22/2015

I bought 4 of the 200W heaters a couple years ago and just happened to stumble upon them again on the BRS website tonight. I was shocked these things are still on the website and listed as BRS recommended! Shocked is a fitting term since 3 of the 4 heaters I bought ended up leaking so much electricity into the water within 6 months that I was getting shocked every time I put my hand in the tank. Through process of elimination and a good voltmeter, I determined that it was definitely the cobalt heaters. Couldn't throw them away fast enough and I'm pretty sure that one of them was responsible for loss of several fish in my quarantine tank during that time. I honestly don't know why BRS still sells these things and still has them listed as recommended. Stay away from them! I just consider myself lucky that no one got hurt from them. I'd give this a zero star if the website would allow it. I love BRS and so really want to encourage you guys to pull this very unsafe product!

I bought a 200w neotherm and was pleased for the first couple months. One night I woke up to a terrible smell, I came to the living room and found smoke rising from my sump. The heater had ruptured right in the center. Some black tar had oozed out from the hole. Luckily I got to it quick enough that no livestock was harmed, but the smell is still throughout the house. This heater is too expensive to have problems like this.

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.
