Less than expected, yet sufficient

Have oriented me to the reviews and bought this little gadget for dusting my computer. I must say, it does the job all, but only in conjunction with pain in his hands. My computer was not particularly dusty, but very uniformly and comprehensively. Large Staubfussel could take off with a very weak air blast, while fine dust surfaces really cost welding. On the whole, I am satisfied, because that's still better than a regular basis to buy any Dusters.
