  • 300 watt finnex By Jeff on 11/25/2015

    I use this product with my reefkeeper and am very happy with how it's setup. The separate display is very helpful for knowing when the unit is running or not so I can monitor any temperature swings. The heater itself is a very good size, and does not stick out of my sump the way my previous 300-watt heater did. This was a great buy for my needs. Thanks BRS!
  • Average By Kev on 8/2/2015

    Suction cups for holding heater in place do not do the job at all.
  • Great Heater By Donna on 7/19/2015

    I'm really impressed with this heater. I've been using it for about 3 months now and it doesn't miss a beat. Just set it & forget it, no more temperature swings. Also love the fact that you can adjust it without getting your hands wet.
  • Great Heater By Kristoffer on 5/28/2015

    I have gone through about a half dozen different heaters on both my 75g reef and 20g reef. This heater is by far the most reliable and consistent heater I have owned. It always maintains water temp with a +/- of 1 degree. I absolutely love this product..
  • 300W of power By Terri on 5/4/2015

    The 300w has changed-there is no separate temp probe, it is now located on the unit. The older model worked fine keeping the temp stable so I will need to see how this new method works. So far, the temp is rock solid. I like these heaters because of the ease of setting the temp and there is no glass to break.
  • The best heater I have used! By Alex on 5/4/2015

    I love these heaters, I have now bought 4 for different tanks and want to get them for the rest of my tanks too... They have a digital readout at all times telling you the current temperature. You set the temp you want it at and it automatically keeps it there, you know when it's on because a red light lights up. The other thing is they are not glass and feel so much sturdier than glass ones. I will only use these from now on, live it!!!
  • Dangerous By Kevin on 4/15/2015

    Two out of three went bad. I went to clean the inside of my tank and got a nice little zap I unplugged the heaters one at a time and then tried them all individually two shocked me.
  • Easy to program By Vladimir on 4/12/2015

    Had this heater for about a week now. Have inside my brute can curing some rocks. Holds temperature pretty well.
  • Never will buy another Finnex product By Furcifer on 4/5/2015

    #1 After owning the HMO-200 heater for 2 months the instructions got wet. I threw them away. I then looked on the Finnex website for a set of printable instructions and to my dismay, they have none. They have no instructions for any of their products. I then contacted them in regards to getting a PDF or a set of txt instructions that I could print. They would/could not provide me with a set of instructions. I really could not understand why a company would not list a set of instructions on their website. Cobalt/Eheim/Aquavia all list instructions on their sites.

    #2 After 5 months of use, I noticed that it was no longer holding to the stated +/-2 degree threshold. One day it would be 72 degrees then the next it would be 81 degrees. I contacted them about this issue. It took them 2 weeks to reply to my RMA request, and they asked a bunch of questions like, Did I try it in a different outlet? Was it hooked to a GFCI outlet? Did I recently have a power outage or power surge?, I answered all of their questions over the course of a week. They then asked me to send it to them. I sent it USPS Priority Mail. It cost $14. A week after they received the heater, I got a reply from them stating that the heater was no longer under warranty. If I would like the heater back, I would have to send them $22 for postage. I explained that the heater was malfunctioning during the warranty period and I contacted them prior to the warranty expiration date. I will never purchase another Finnex product again. Their measly 180 day warranty speaks volumes about how much faith they have in their products. Especially since companies like Cobalt Aquatics and Eheim all have 3 year warranties on their heaters.
    From their website:
    Products are warranted by JSK Merchandising Inc. To the original purchaser against defective material and workmanship under normal use for a period of 180 days from the date of the original purchase.
  • Great So Far By WLR on 3/6/2015

    Heater has been installed for about two weeks and has held the set temperature fine. Unit appears to be calibrated correctly as I have checked it against a glass thermometer. If the unit has any issues I will update the review to let others know my experience. Right now though its rocking!
