    Affordable price
    Low power consumption
    Nice design
    Very accurate readings


    Contrast with blue Backlight could be better,
    amber would give a better contrast.


    I Compared this device to a calbrate volatge source, the readings were usually within +- 10mV of the source voltage.
    At the back of the device are two potentiometers, i think they are for calibration, but since my device worked well, i did not test this.

    Power consumption was ~8mA with background ilumination. Without ilumination (cable unsoldered) power consumption goes down to ~3.6mA.


    Very good value for money, the device works well, the readings are very accurate and the power consumption is very low. The device could be connected to a car batterie for months without noticable drain the battery. This is even better if you disconnect the ilumination.
