Was looking for a small 0-1Vdc meter that would work on 2 wires. This analog gauge is great value for the price, since I tested it's accuracy and found it to be spot on. Only downside was that customs added some time to the delivery.
Accurate and does what it's designed to do. I installed blue LEDs to highlight the meter and illuminate the needle pointer it displays the bias voltage of the el34 tubes on my amplifier
