Review on 🌡️ Aqueon 7.5 Watts Flat Submersible Heater by Roger Calvert

Loved the shape/size of the heater. The reviews said that for a 5 liter tank is great. I received it, read the instructions and put it in the tank. It didn't get warm at all. I turned it off I tried that, it didn't work. I read the instructions again, nothing. So I unplugged the whole outlet and still nothing. Very disappointed and frustrated as I was looking forward to this cute heater. I have a 5 gallon Marineland Portrait tank with Cockfish and 2 Scarlet tubs. i want it to work I would recommend doing some research on heaters before buying. After contacting support, it was completely replaced and it ended up working perfectly. The advantage of this product is that it is thin enough to be hidden or submerged in an aquarium. While he's working, he's doing his job. Cons, it's unpredictable but at the end of the day it works. I recommend this but with caution as it can be buggy.
