I am all for anything that makes house cleaning easier, and while the general concept of this product is good, the actual "duster" is a bit on the skimpy side.  The pictures and commercials make it look  like it is big and fluffy, while it is actually a bit thin.  Also, instructions for how to attach the duster to the wand are not clear.  All that being said, it did pick up dust just fine.   Being cost and environmentally conscious, I generally do not go for disposables, but prefer re-useables. Once this thing is full of dust, it just goes into the trash.
