High quality build, but the thermostat is sub par By Garrett on 3/10/2017

My Jager never was able to run without a 4 to 6 degree fluctuation, so I had to get a thermostat and not use the sub par thermostat. However, it is built very nicely, so once I got a thermostat, I had no problems. This is not a deal breaker because most heaters should be run on a reliable thermostat, anyways, to avoid failure.

This heater is spot on after calibration. I use one in my sump and I have another one I use in my salt mix container. Always spot on

As I unpacked the 300W Large Heater, I was worried damage had occurred during shipping. To my delight, I saw the packaging ring had done its job with three broken prongs, but no damage to the Heater itself. It came preset to 79 degrees F and after 48 hours I checked it with my Fisher Scientific Thermometer to be accurate within 0.2 degrees. I am satisfied with the purchase and will probably buy another one in the near future.
Works well... reliable and price is reasonable By Gino on 2/24/2017

I have four of these heaters... two in my sump which are controlled by my Apex system... one in my mixing tank (just using its own thermostat)... and another that is a spare except for when used in a quarantine tank. The ones that are controlled by the Apex keep the temp within 0.2 degrees F. The one in the mixing tank reads a bit low (i.e. the water is slighter warmer than the setting on the dial when checked with an external thermometer... but works fine) I have the same complaint as others however... they are fairly long and you need a larger sump for them to fit nicely.

I hate this heater my QT tank heater from Petco is far more accurate than this junk, on every setting I wait 12-24 hrs for re-adjustment and it fluctuates 2-4 degrees, I had it set to 78 24hrs ago and this morning water temp at 82 and claiming so I re-adjusted and lowered to 78 again waited 1hr and the thermostat still is on so I lowered again some more and forgot about it and went to work, so I am hopping I don't get back home to a aquarium full of dead fish.
This should not be so complicated for a simple heater and for less than $30.00 you have the risk of loosing everything.
Great heater for the price By Matt on 2/6/2017

About a year ago I went through several heaters before stumbling upon the eheim jager trutemp. I purchased a brand new 200w jager trutemp for my 75g reef tank and I was having problems with the heater fluctuating temps drastically. After emailing the manufacturer they promptly sent me a brand new replacement and I've been using it every since!

Used in Mixed Reef 120G, Temperature variation of ~1F using my Apex Controller, no problem and work as intended. I wish they had a shorter design as it can be challenging to find a good spot for a 18" Heater. -1 Star for the length.

I really like these Jaeger heaters. They work well and are dependable. Simple to use. I never have any problems with them. When I worked at a LFS, that is all we used.
Heater is good but too long By Tony on 12/30/2016

I have used these heaters in the 200w for many years, but recently I upgraded to a new sump with baffles... And the heater won't fit anymore. Most heaters in the market arent this long. They're good but too long!!!

Great heater, agree with another reviewer that they are sometimes too long for their ratings, but otherwise excellent. Should have bought this heater first.
