    Never have a voltage question again
    4 Stars
    Never have a voltage question again
    The only thing keeping this from a "5", was the lack of strain relief where the wires come into the meter, and knowing me.... I would break that out by accident. This would reduce the chance of the wire insulation getting broken there at the wire entrance. The wire jacket does not go into the meter.My fix... hot glue gun. I put a dab of hot glue covering the red/black wires, and used the included plastic protector on the meter to press it flat/inline with the meter back surface.Pressed in place on my truck with 3M 03609 double sided tape and it looks AWESOME!
