Great heaters. I am currently running 3 of them in two tanks. All have worked flawlessly.

Pros: M

Cons: Suction devices can lose grip over time

While this heater may cost slightly more than others, it is well worth it. It is very durable and reliable.

Over the last 15 years, I have tried many brands of heaters and Ebo jager is my favorite.

The glass is thicker than others !

Pros: Durable & reliable

Cons: none

I've been using two of these heaters in my aquarium for about 9 years now. Haven't had any problems with them. It takes a little time to tweak them and get the perfect temperature, but then you can just forget about them.

Pros: Does a good job

Cons: none

I have owned numerous sizes of these heaters through the years,and have never had any problems with them,as they seem to last a long time.
I have two different ones in tanks right now.
A good basic heater.

Pros: easy to find stands up to use

Cons: none
