Y’all let me just tell you I’ve never been one for dusting, but these babies are a game changer. I went from dusting once in a blue moon, to dusting weekly. It takes me all of 15 minutes to do my whole house, and then I pop the head in bin. I might have spent $20 on this big box of them, I don’t really know, but I probably won’t go back to dusting any other way. It amazes me how much dust collects in just one week.
