I recently bought two Eheim Jager Submersible Aquarium Heaters online. I tried the first one and am surprised that it seems to be a lemon. I thought they were so simple that a German heater would be unlikely to be defective right out of the box.
Should I try the 2nd one or return them both for a different brand?
Thank you!
p.s. I wonder, do people counterfeit things like this?
