the usb vac be very low quality . it be basically a fan with a little nozzle on it . now remember when I say fan ? well , a fan do not a vacuum make . sigh . the not-a-vacuum usb noise maker also break while I be try to make it vacuum . I do not force it , I be not rough . the nozzle fall off and refuse to be reattach without some serious grunting and cussing . Metro Vac make a $ -lrb- ... -rrb- version . I hate to spend that much money , but I hate for thing to be icky dirty even more . what a spectacular waste of -lrb- ... -rrb- buck .
