Review on ⚡️ Onyehn Voltage Controller 1803BK: Adjustable Solution for Industrial Electrical Systems by Rick Vidaurri

Even when the handle is turned fully counterclockwise and locked in the so-called off state, it's not really off. I ordered them from this company but they deleted the page before I could write a review. After hooking it up to a small hobby motor, it turned on the moment I plugged in the power supply. This is a dangerous device.
