Review on Revolutionize Your Aquarium with the Jebao SLW 🐠 Series SINE Wave Flow Wave Maker Pump and Controller by Josh Suter

Shaft generator works as expected, no complaints about functionality. As some people point out, the magnet is very weak. I just installed a SLW-20 on the Fijicube Peninsula weighing 38g. The glass is 8mm thick and the magnet barely holds without falling to the ground. The pump itself would have tipped off the glass without the included suction cup for cord management. Divide between trying to find the best magnet and sealing it or giving it back.
