    Its relatively easy to operate when you figure it out.
    Its compact, portable and it has output generator (square, lowbitrate-sinewave, triagnle, saw) with adjustable frequency.
    2-analog inputs, and 2 digital.
    Battery big enough to finish your measurement, without need of charging. :)


    Its hard to operate it at first, but you will get to it.
    Capacitive calibration is problematic due construction of the input section.


    If you search for relatively cheap oscilloscope that can show PWM, and you are okay with a little inaccuracy of measured voltage (+-10%), then its yours.
    If i was looking for pocket oscilloscope it will be definitely next buy.


    Max input voltage 80Vpp
    Charged via USB, runtime on battery havent found yet. (1000mah lipo) - pl384070
    I recommend, when you buy it, to remove the back cover and adujst those sharp points on it that could damage the battery.
