Review on 🔥 Ehm Heater Jager 300w: Powerful and Efficient Heating Solution by Lisa Ramirez

I purchased this heater on May 16th, 2021 and have followed the calibration instructions. Also, I went to YouTube to make sure I'm doing the right thing. Let me just say this heater is out of control. I was lucky to check my water temp today and it was 90 degrees. I didn't turn the thing off to keep heating the water and I'm very lucky my fish didn't die. 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 another heater because it's over 30 days old with amazon or the seller I can not start anything.
