    Yes (1) Color: Black
    Works but lacks a guide
    It's working well, but it was a little complicated to get it working as there were no explications.
    You'll need an additional 0,015ohm shunt resistor, connected on the ground/negative.
    No explication/guide

    Yes (0) Color: Black
    Easy to read display
    The reading of numbers is very easy, big digits.
    I was a little confused with needing or not a shunt resistor. Now I think that it needs it.
    The shunt is needed.
