The Centrobulb you recently shipped to me came with an note which states that it "operates most efficiently in the vertical position." You previously stated (in a Q&A) that it should *not* be used vertically. Do I have a newer type of bulb? In any event, I am having a great deal of trouble with clogging. I filled the bulb about 1/3 full - is that too much, too little? Shaking only helps temporarily. Any help would be greatly appreciated (I am using Drione dust in the duster).
Yes, the Centrobuld has been updated since 2011. As for the clogging of the Centro bulb duster, you can place a marble or rock in the duster. This will prevent the dust from getting clumpy sometimes in humid or moist conditions and prevent the duster from clogging. A marble seems to work very well. Let us know if you have any other questions.
