This review is from: Tech Vac - Computer Keyboard Vacuum (Office Product)
I bought one of these second hand from a charity shop and the suction it produced was barely detectable. It was simply incapable of sucking up any dust. Now whether or not a brand new one would be okay I can't say, but there didn't seem to be anything wrong with my second hand one, the motor gave off a healthy 'full throttle' sound. I'm not sure it had ever been used anyway, as I could see no trace of dust at all in the collection tray; I reckon it never was any good and whoever bought it brand new had just stuck it in a charity shop.
