Review on DROK 90483 8A/100W DC Car Power Supply Voltage Regulator Buck Converter, 12A Max, DC 5-40V to 1.2-36V Step Down Volt Convert Module by Hesham Peltier

I'm so glad I wear glasses and didn't lose my eye when it exploded in my face! Sitting at my desk doing electronics or soldering, my head is about a foot and a half from the surface. Capacitor C1 failed, the board exploded straight up and the aluminum case hit me in the forehead. The paper, foil, and internal parts of the condenser looked like tiny splinters. Minor cuts, more than skin tears and yes. The back of the board had sticky residue and "chalk" leaks on it. I have NO load on the circuit (open circuit). The source was 14.8 VDC connected to "IN" on the board. The output was connected to a digital voltmeter to monitor the output voltage and regulate it to 12V DC. explosion).*EDIT - I tried to post with an angry word (meaning I "peed") and I had a photo of my bloody forehead. I guess they didn't want it either, so I removed them and here we are. Now I can't add photos of the faulty product.
