Great heater for the price By Justin on 4/29/2014

Does the job for prepping water temp for water changes. I like the external temp probe to easily tell me when my water is ready. I do take some of the advise from users above and would hate to use a cheap heater on my main system so I keep a Fluval E heater on main. Great bang for the buck Finnex.

What can you expect for the low price. It works, so no complains here. It's been holding the temperature steady on my 30 gallon.
QUIT AFTER 2 MONTHS By KIM on 1/4/2014

I started using the 300 in the sump of my 100 gallon system just over 2 months ago and discovered that it has quit working already. With the amount of money and attachment I have invested in livestock I can't afford to have a heater quit working on me like this.
worked great until I saw moisture inside By Mr.Tomek on 11/24/2013

This heater worked great for me for 5 months and I started to notice moisture on the inside of the white sand that is around the coil. Since I have alot of corals and fish that are worth big $$ I didnt want to risk it so I went out and purchased a neo-therm. Better spend more $ on a better heater then losing your livestock to a failure. hope this helps.

Don't let the price fool you. This budget heater has been in my tanks for quite some time and had no issues. I wish they made a smaller wattage version for my nano tanks.
priced right By pickpoo on 5/7/2013

I 've been using this heater for over a year, and it's been holding the set temperature pretty accurately. Priced right too.
Great heater! By James on 4/4/2013

I bought the 300w heater and it works great. It's a great heater at a great price, couldn't ask for better. It keeps my tank at a constant 78°. If I ever need another heater, I will definitely purchase one of these.

The finnex heaters been working great for over a year. It's the best heaters I ever owned and the price was right too. Don't know what everyone is crying about. Mines works great!

They come with a 6 month warranty, mine was dead at 11 months. Spend a few extra dollars and get a better heater.

I bought two of the 300 watt models for redundancy on my 115 gallon, which were controlled by an Apex. Both have completely stopped heating after 8 months of use. If you don't mind putting your expensive livestock at risk with a crappy unreliable heater, than go for this Finnex. If you prefer reliability in your equipment and stability in your system, choose a different option for your heater(s).
I've lost that loving feeling By David on 12/14/2012

Initially I was really impressed with the Finnex heater (200w). Love the digital readout plus it has an external temp sensor. However, a little over a year has passed and it will no longer heat the water above 74 degrees. Not a catastrophic failure of course but still disappointing.
Not Reliable at All By Todd on 12/6/2012

I've gone through two of the 300W in under 2 years. Both times the electronics failed and the units would not turn on, nor would they display current temperature. Not good hardware at all!
