Review on 🌞 bayite DC 12V Solar Water Heater Circulation Pump with Power Supply Adapter - Low Noise, 3M Head, 8LPM (2.1GPM) by Gerardo Goodson

Power supplies SHOULD NEVER make that much noise. Buzz means lost connection or bad soldering, which means sparking, which means heating. I expect a fire any day now. UPDATE: This device has actually stopped working. After disconnecting and opening the power transformer (the end of the cable with a large plug), all the components burned out. Luckily it failed due to an open circuit, not a short! UPDATE #2: Two days after his death while waiting for a replacement pump (not another piece of Revain junk) the pump housing leaked leaving 15 liters of water everywhere.
