This garden dust applicator is just fine. It works, and it holds a good supply of powder. Though plastic, it seems to be pretty well made, fits up nicely, and is sturdy. But you do have to hold it just right or you get almost nothing coming out....I dunno, maybe that is the case with all dusters of this type. And it makes a dreadful squealing sound with each stroke of the pump, but it doesn't affect the function. All in all, I would say it was definitely a good buy and certainly a much cheaper option than a power duster.

I had a bug problem in my home garden and I had owned an ancestor of this type of duster. It was given to me by an elderly gentleman when I gardened out in the country here in North Carolina. It was misplaced years ago. I had since used a pump liquid dispenser for SEVIN. It was OK but liquid SEVIN is very expensive. You cannot imagine my joy to find it here on Amazon.com. I immediately put it to use.
This is a simple yet very durable tool. I just dump some SEVIN dust in it, screw the top on and I am ready to go. One can dust as lightly or heavily as he or she wishes. Just be careful not to breathe the dust in. It is easy as one can see the way the dust is blowing. Use this in 'no wind' or 'slight wind' situations for best results. Morning or evening is best.
This duster is stoutly built, but not unbreakable. It is built of plastic, but a very durable thick plastic. I judge it to be as durable as any duster made. It is better than the metal duster I once had.
This duster is a LOT more economical to use (with SEVIN) than any liquid duster I owned. There is no maintenance to it - just keep it in a dry place when storing it.
I gave it a five star rating -only because I could not give it six stars.

This duster is pretty good. It gets the dust under the leaves without spraying into the air. The wand tends to fall off if it isn't pushed on tightly - twist it on snuggly. Easy to clean and store.

Although this unit will not perform like the crank models that cost 3 times as much...it will be fine for smaller area applications like roses or potato patches, etc. ...just expect to do some shaking of the unit while pumping in order to keep the duster primed. The large fill mouth is a real plus! I am not much of a plastic fan, but this unit feels stout and it will not corrode like the old tin units used to.
