    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:

    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. :)

    Cons:

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

    OtherThoughts:

    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.

    Bottomline:

    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.
