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.
Cheap but works By Stacee on 3/7/2014

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
KIM wouldn't recommend this product to a friend
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.
great budget heater By Dr. Hook on 5/21/2013

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
David wouldn't recommend this product to a friend
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!
Bought 2 Both Broke By Steve on 11/16/2012
Steve wouldn't recommend this product to a friend
I purchased 2 of the 300W heaters just under a year ago. The first one literally started on fire in my sump. The second one just stopped heating even though the display still works and says it is.
Will not purchase again.
3 heaters all broken after a few months By Matt on 11/5/2012
Matt wouldn't recommend this product to a friend
Awful product, do not buy! Bought a 100w and a 300w for two different tanks. Both broke after a couple months. Had the 300w replaced by Finnex, but that broke after a couple of months as well.
Clearly there is a problem with this heaters and I at least wanted the 300w replaced again since I was still within their warranty period for the replacement. But nope they wouldn't do that because the replacement didn't fall within the time period of the original purchase warranty period so they refused to replace the heater.
Reply from the company was that they aren't meant to be run all the time and maybe my room temperature was too low or the heater is undersized for my tank. My 200w aqueon heater has had no issues with running the tank. Now I have a controller and my duty cycle shows its about 25%.
Do not buy from a product or a customer service standpoint.

Questionable product, possible manufacturing issues By Nicholas on 10/11/2012
Nicholas wouldn't recommend this product to a friend
I purchased a HPS-100 Finnex Digital a year ago and it simply stopped heating. All the indicator lamps were working but no heat.
I purchased a second HPS-100 Finnex Digital to replace the first. I'm now having problems with it after running it for 3 weeks.
I would recommend steering clear of this product and spending your money on something else.
Good Heater By David on 10/9/2012

I bought this a month ago it is easy to set, it stays in place, and keeps the temperature consistent; for the price it is a good heater.

Bought the 100w heater in march, it's september. Haven't had any problems with it. I would say that the tank sizes for the heaters are a little off, it has a hard time keeping up on chilly nights.

What sets this heater apart is the external thermometer probe and the digital readout. It makes it easier to set the temp...rather than guessing.

Bought this a while back and hasn't failed on me yet. The LED thermometer provides great feedback and the one button interface provides simple yet versatile performance.
Temperature reading is not accurate By Seth on 9/7/2012
Seth wouldn't recommend this product to a friend
I bought two 300W models a few months ago to go into my sump for a total system volume of 240 Gallons.
They two heaters are installed side by side with the temp probes in the same area. One meter reads 78F, the other is 76F. It's hard to say which one is correct, I will need a third temperature gauge now!
High Tech, Poor Quality By Jared on 6/3/2012
Jared wouldn't recommend this product to a friend
I purchased a 100W just over 6 months prior to this review. Today, the heater has started reading '99' no matter where I put the probe. I would stay away from this brand until they figure out their quality issues.
questionable perfomance By Dale on 5/23/2012
Dale wouldn't recommend this product to a friend
Bought 4 100w and 1 200 watt for fish room tanks (20H & 30L gallons) and DI water tub to replace recalled Marineland Stealth heaters. Seemed to be reasonably priced. Would be better if they filled tube with black sand instead of white to blend in with dark back of tanks. Minor point. 200 W in DI tub still going strong after over a year. 2 of the 100 W have stopped heating after about 4 months. 3 month warranty is really totally useless. Bought Finnex metal heater with anlog control at same time for 20L tank since it is much shorter for the shallower tank. This has been working fine. May look into these for future replacements but may be scared off Finnex brand.

I have been running this 300w Finnex HPS heater on my 90 gallon with 36 gallon sump for two months now and love it. It is easy to dial in at any temp you want with a digital screen to 0.1. Comes in very handy when wanting accuracy and stability for any aquarium. I am actually buy a second one as I am tying in another 50+ gallons to my existing set up. Great product.
