"I am far more likely to use a microfiber rag to dust, or my vacuum when cleaning, staying away from gimmicky products.....BUT this thing is GREAT! It makes for a more efficient process, gets around and behind things with ease, and holds a whole bunch of dust! My step-mom gave me my first one, and I'm hooked! I'd like to be able to purchase the REFILLS on Vitacost, not just the kit, since that's the idea of having something with refills, but I can get those at the drugstore, too. Great on electronics - doesn't scratch. Just shake out frequently so the bunnies don't gather."
