20 years in the hobby and the only heater I will ever use is a Jager. No other heater has ever held my tank so steady as a Jager. if you have never used one, I recommend them fully.

Unit that I received was off by 8 degrees and unable to be calibrated correctly. The dial is really hard to turn and the heater turns on too low and turn off too hot. Eheim's Canadian customer service is really bad. Got hang upon even after number 1 in line five or six times and no help whatsoever. Return to dealer, they said or pay to send it in (to Canada). It's only 4 months old and sat on the shelf for 3+ month. EHEIM = Not for me, thanks, I can live without the aggravation, hype and the high price. There are better options out there for less.

It's not expensive, it doesn't break, it's easy to use, and it gets hot. What else could you ask for? I've been using these for a long time, and I won't waste my money on other products. I've found what works. Do a google search for "longest lasting aquarium equipment" and see what products come up. This is one of them for a reason. Only thing is.....they are a glass type product. So if something smashes into it hard enough, it will break. This isn't a design flaw, or the product's fault. It's just how a glass heater is. So if you keep super big fish that like to smash into things inside the aquarium (Dovii, etc...), you might look into a titanium heater if you run your heaters inside your display tank, or get an inline heater, or run glass heaters outside the display tank (in a sump, etc...). I use these in my sump, and they do great!

I just recently replaced my old Stealth heater with the EBO Jager 50 watt in my 10 gallon beta tank. It has been a week and so far I love it. The temperature stays stable and hardly fluctuates. Cons: The only bad thing seems to be, you must calibrate it yourself (which isn't as bad as it sounds). I have the thermostat on the heater set to about 77* but it really only heats to 74*, so there is a couple of degrees difference between what you set it on to what it actually heats to. Overall it isn't that bad, I'm just taking a few days to keep upping the temperature until my thermometer reads what I want it too.

Bought this as a replacement for a recalled marineland heater. Dropped this in and it's provided rock solid stable temperature. Seems well made. My only issue is that it has bright white lettering and a blue temp dial. I like to have this stuff disappear but the colors make it call attention to itself. But otherwise great heater!

I've owned this brand of heater for over 20 years, and have NEVER had a problem with it! It's a very dependable unit and keeps the water temp. steady, consistently. The heater also lasts a long time with no operating problems. I HIGHLY recommend this heater!

Got a 150 watt for my 55 gallon a couple years ago and have nothing but good to say about it. It maintains a steady temp, is accurate, a very solid little heater. Adjustment dial is easy to read. I will stick with this brand for future heater purchases.

I bought the 200W heater for my 55 gallon tank. After I ordered it I realized that maybe it isn't fully submersible. I did a little research, and it seems that the EBO Jager Heaters were not UL listed for the United States to be fully submerged. I even called Petmountain to check, and they confirmed that. They were also willing to waive to restocking fee if I wanted to return it. When I got the heater, the package stated that it is now UL listed to be fully submerged! Problem solved! The heater is working great and keeps my tank at whatever temp I set. I'm glad I bought the best quality one and that it can be submerged. I like the indicator light and the ability to recalibrate it if needed.

I have had mine for 3-4 years now and it is well worth it to get one. I have a 250watt one on my 225 gallon tall and it keeps all that water heated at 78 degress.

On February 7, 2008:
I have 2, 200 Watt EBO's and they work great. I keep one in my Sump and the other in my batch of Salt Water I use for water changes.

On November 23, 2007:
Best price and this is professional stuff.

I've had my 150W heater for going on 3 years with no problems. Great product!

I've owned this heater for years and it has proved the test of time. The price here is also better than local stores.

After being a former aquarium enthusiast, with several "meltdowns" with heaters, I understood why you never skimp on the heater. So when I first set up this 34 hex aquarium in 94, I wanted the best heater on the market. Ebo-Jager was highly recommended. This heater truly was the best I have ever used. Temperature NEVER fluctuated, and it worked flawless for 10 years until the heating coil burned out. I obviously replaced it with another Ebo-Jager, but it was not the same. The simple protected temperature adjustment slot was replaced with an outside dial, that needed calibration by the consumer to work properly. After figuring out how to work this, I had the tank temp stable... until 13 months later a meltdown occured (out of warranty). I figured this was an anomaly, so purchased another ebo-jager. Within months, this heater couldn't hold the temp. A third was purchased, and this too failed a couple of years later. Apparently ebo-jager was bought up by another company, and they must have changed the design and quality. 3 bad heaters is not a fluke. If you are considering them, think again. They are living off an OLD reputation.

Had this heater for close to 10 years now. It has reliably maintained a steady temperature for all these years. However, the one gripe I have about this is that the thermostat is not properly calibrated, at least on my heater. The temperateure is about 5 degrees too high, so to set it to 80 I need to set the thermostat to 75. This might just be bad quality control on my particular one though. Would've given it 5 stars otherwise.

I love this heater! They are made by German engineering and usually go for about 40 bucks at the pet stores! These are a steal here!

This is so easy to use with the best results! Definetly what I expected and more!
