Review on bayite Mini Digital Current Voltage Amp Meter: Accurate & High-Precision Gauge with Hall Effect Sensor Transformer (5-120V, 100A) by Rafael Lewis

Useless counter. First, it cannot be mounted without major modifications. Designed for panel mounting, but the front flange is tiny and the rear compression flange is tiny and no less compressed than the front flange. Then to switch from volts to current you need to press a small button mounted on the back of the exposed circuit board. Why put a mode switch on the back of a product that needs to fit in the panel? You have to disassemble the panel to switch from volts to amps! Then when the power comes on it flashes so brightly that if it was installed on a boat or van it would keep you up all night or drive you crazy. must have happened to the engineer who designed it!
