“Long and Reliable”

4.0
I have used six Eheim Jäeger heaters over the past 10 years for various tanks and mixing vats. I have never had one fail on me yet.nnThey can be too long for tight spaces.nnHysteresis is fairly tight, but the temp dial on top is really just an approximation of actual temp setting.

“300 watt”

Great heater. Only thing to keep in mind is the length "20 inches" if you want to stand it vertical in your tank. Easy to set and holds temp. Good value.
