  • Not calibrated By on 9/7/2017

    I have had this heater in service for a couple of months now, and the temperature is consistently 2 degrees lower than it reads. It seems to keep a consistent temp at the setting, just 2 degrees low. Will be looking at other options.
  • Not calibrated from factory correctly By on 7/26/2017

    It's about 5 degrees off. I have 3 thermometers that are all within 1 degree of each other. They all show 79 while this thing shows 84. I'm trying to start up a new tank here but I don't really trust this heater. I'll keep an eye on it while the tank cycles. I'll just have to set it 5 degrees high but Definitely not putting any fish in until I'm sure this works.
  • Mediocre Heater with Terrible Warranty Period By on 7/14/2017

    Bought two, have to keep both set at 84 to keep the water at 78 since the heating element and probe are not well isolated.

    Then 10 months after purchase one died, and the warranty is only 6 months. I'd expect at least a year warranty on something like this.
  • Great control By on 7/3/2017

    I like this heater because it will not shatter with glass. Also the controls are easy to read and set. It’s reliable and fits in the back chamber of an AIO.

    I dislike the hook attachment to hang the temp reader because it was easily lost and now I just free hangs
  • Good Little Heater By on 5/27/2017

    Works good for me. Have had the 200w for over a year no problems. Just got the 300w for my new tank and like the small size for a 300w heater.
  • great product By on 5/18/2017

    I own several of these 300 w units, the first one lasted about a year, the second and third one are still going strong, still working after 2 years, I did just purchase a new 300 w unit and was impressed with the new style heater, the temperature line is now combine within the unit instead of a second line running off of the unit. more stable.
  • Failed after 1 year By on 4/9/2017

    Almost 1 year to the day after installation the heater failed. The warranty is 6 months. My expectation would be this product would last longer than a year and the warranty should be at least that long.
  • Inexpensive and worked well. By on 4/1/2017

    I bought this item for a small isolation tank. I had another brand heater without a control which was supposed to keep the aquarium at 78; but it kept it between 80 and 81.5. This is too hot for me. So I bought this. I set it at 77 degrees and it keeps the tank between 76.1 and 76.3, which is where I want it (I have a good reference thermometer). This is perfect with little variation. I know these have some negative review, but I have had good luck with it.
  • Great heater By on 3/24/2017

    I've have had this 300 watt Finnex HMO heater in my tank for over 3 years and it has kept my tank at 80.5 degrees since day 1
  • One Month By on 2/6/2017

    Ceased to operate after only one month of use.
