Review on Boxtech Hang On Filter Aquarium Power Waterfall Suspension Oxygen Pump - Submersible Activated Carbon Biochemical Fish Tank Filtration Water System - Wall Mounted by Robert Smithlin

Two of these little filters have worked for me for less than two months. At first they seemed good - very weak, but it was good. However, today I cleaned my aquarium and found that the filter is not working. I turned it off and noticed that it was so hot that touching it burned my fingers and the pump housing had melted. There was no debris inside, but a small fan-like piece had broken inside the device. I'm glad I noticed before it caught fire or something.
