🔥 Ehm Heater Jager 300w: Powerful and Efficient Heating Solution Review

Eheim used to be a great quality product. I have been using their aquarium products for decades. Now the last two heaters I bought have failed within 30 days.

This is clearly a used and returned item. He doesn't even have the necessary equipment. I will be compensated for that. I am extremely disappointed.

I don't know if I got a bad block because I read all the reviews for this product and people said it's a good heater now I have to pay for…

Received in excellent condition as expected. It maintains the ideal temperature of 78.5 degrees in my 55 gallon fresh water tank. I thought I had enough room to mount this heater vertically in my tank, but I didn't. My tank is just under 24 inches, but even with the heater end down to the gravel dug glass bottom, it barely made it past the minimum water level gauge.
