Not happy By Vincent on 1/30/12

I purchased one of these 300 watt heaters recently because of the reviews. However, I am not impressed. The first one I had shattered inside of my sump for some unknown reason. BRS was great about it and sent me out a replacement the very next day. Tonight when I came home I noticed that my tank was down to 74.5 degrees when I keep it at 80 degrees. For some reason the heater quit working. I tried troubleshooting without success. I will not by one of these again.

I purchased the 300w heater and it worked great, I was really happy with it. That is until is stopped working yesterday. I contacted Finnex and am waiting to hear back from them on a warranty replacement.

I have owned 4 of these heaters in the last 6 months, only one of which is still working. QT heaters thermostat malfunctioned killing my poor fish. Other two just stopped working after 3-4 months. Thankfully I use two heaters in my DT so the whole tank didnt crash. they look nice and have a nice price tag but aren't reliable.

i really like my 200w finnex heater. the digital display is great and has proven to heat accurately against my two other thermometers in the tank. great value!

Seems like value but doesn't last long and poor warranty By Matthew on 12/12/11

My QT HPS-100 quit working on me after about 3-4 months of total use, of course this was 8 months after I purchased it (only used QT a few times)so Finnex wouldn't replace it.

Unfortunately, I purchased a HPS-300 for my display tank right before the HPS-100 stopped working (big mistake). That HPS-300 lasted about 2-3 weeks of use before it stopped heating, nearly killing off my tank. In the process of getting that one replaced.

Seems like a lot of value for a heater and a very nice package/design. But from my experience over the last 8-9 months I would not recommend this heater series to anyone. One lasted about 3-4 months, while the other one lasted about 2-3 weeks. In addition, with a warranty of 6 months from date of purchase I would never risk purchasing this heater again.

so far so good By John on 12/12/11

I just got two of these and they work real well. Time will tell how durable they are. I really like the digital temp display, so it is easy to see when they are on in my sump.

Only one complaint By Mike on 12/10/11

I'm happy with the heater overall. Very easy setup and holds temp in narrow enough range. My only problem so far is that the suction cups slide around on the glass. I'm not sure if it's due to algae film on the glass but my other in tank suction cups haven't had any problems. This one started sliding around after about 4 days. However, the cups are holding the heater in place at this time so it's alright for now.

Awesome! By Aquasapien on 11/26/11

I buy a lot of my tanks off Craigslist and a lot of times a heater is included. So, I've tried a ton of heaters and as a general rule I hate heaters. So recently I did some searches and it seemed that the 'ol Jager was most often used.....BUT I saw these and thought I'd give them a try. I bought 3 Jagers and 4 of these last month and so far I DEFINITELY prefer these!! I have a thermometer in every tank and double check with a handheld digital and these heaters keep my tanks within +/- 1 degree all the time and have been flawless in operation. One of my brand new Jagers ran away one night and there went that tank!! I'm going to continue to buy these heaters from now on. If I get a bad one, I'll write it here. Why pay more for heaters that cook or chill your tank? I'm so glad to have found these heaters!!

Outstanding!!!! By FuDz CWerner on 11/25/11

I have 2 of the 300w heaters and both of them perform flawlessly. I use one in my 75g aquarium and it maintains the temperature +/- 1 degree without any problems. I use the other in my 50 gal water change rig. It can heat 40+ gallons of cold RO/DI water to 78 degrees in under an hour with the recirc pump running on the rig. The only heater I had before this one was an Aqueon which burned out in 6mos. I highly recommend this product! Don't be scared by the low price.

Best heater I've had By Ismael on 11/15/11

Had many heaters in the past this one was the least expensive, but don't let the price fool you. It is very well built, easy to set and keeps my temperature +\-1 degree. For being the least expensive it has outperformed all other heaters I've had.

I love this heater. It shows a digital temp of your tank. Very accurate and very well built

I decided to purchase this heater based on the fact it only had positive reviews and a lot of them. The heater has worked flawlessly in combination with my RKL controller. Temp has stayed within +/- 1 degree.
