Great heater, but integrated thermocouple causes issues. By FishersCoralReefFarm on 5/8/2016

I have two of these. 75@ with the separate thermal probe and a 300W with the integrated thermal probe.
I have the 300W heater on a 130-gal system with a 79-F set point. The water temperature of that system, as measured by a calibrated digital hand-held meter, reads 76-F when the Finnex controller displays 79.
If I unplug the Finnex heater for 15 minutes and plug it back it, the digital display shows a temperature of 76-F for about 30-45 seconds. But, after the heater has been on all that time, the digital display on the Finnex climbs and within 2-3 minutes reaches the 79-F set-point, at which time the heating element turns off. A sample of the water reads 76-F with the hand-held digital thermocouple.
I believe that by integrating the Finnex temperature sensor into the heater body itself, leads of a falsely elevated temperature. I can choose to simply raise the set-point of this heater to 82-F and cross-check with my hand-held, but I am taking a risk by relying on a temperature bias that might not be there one day.
I still recommend this heater for it stability, clean-ability, durability. But I am planning to by a separate external thermal controller . I believe this will work, as the Finnex retains its set-point during power loss. I’ll just have to get okay with the idea that every time the external controller turns on power to the heater I will hear a quiet beep.

Bought the 300, I've had it only 3 weeks, no issues so far....
1st one was great. 2nd and 3rd sucked By Davo31 on 4/28/2016

I bought one of these a year ago and loved it so much I bought a back up a few months ago. The 2nd one wouldn't turn on so I got a replacement from brs. Then that one lasted 2-3 weeks before it quit...... And my original from a year ago finally gave out this morning. Im kinda thinking it's the LED portion breaking and not the heater itself. Each heater would get around 10 degrees off before it would just start flashing/ not turn on. Either way I will not be buying this brand again. And now I'm forced to buy a aqueon pro (it's too big for my liking) for Petco because I need a heater now.
Side note: BRS did an amazing job at customer service. There were some hiccups but they kept in contact with me and I'll definitely keep buying from them in the future

I have been using 300 watt heater for four months in my 75 gallon reef tank. I keep it set at 79 degrees. It keeps the tank within a one degree range. The suction cups are not the best and I needed to add my own. The memory feature is nice. Overall very pleased with this product.

I am using this product to heat my saltwater to be used in my tank. It works quickly and seems to be accurate on the temp it is heating to. I like its quality.
Good Product for the price By Chris on 3/24/2016

I have only had the heater now for about 1 month but overall it runs great. Good display with temperate gauge built into it allows you to set the temp to your desired temp and also see the current temp. It does seem to be off almost 2 degrees, but it holds a consistent heat for my 55 gallon tank. I run a 200 watt, and I would recommend it.
Great, consistent heater, nice digital display By Becky on 3/18/2016

Nice sleek little heater, suction cups work nicely. I really like the digital display and it's little hook for hanging, however the cord between the heater and the display / controller could be longer to allow more placement options. Keeps a consistent temperature and seems to be durable.

I really like having the digital temp readout. I have been using this for about a month and have had no issues.

I'am new to saltwater and have tried other heaters. This 300 watt is by FAR the best heater so far. Keeps a consistent temp. Very, very pleased with this unit.
