This thing is amazing. The way it works, it absorbs dust into itself, and not carry the dust as you sweep the car. Thus, it does not scratch the surface. The only negative about the CA Duster is that you have to keep it in it’s own little bag, so it doesn’t get dusty just by sitting (remember it attracts dust?), and also, I did not find the way to clean it yet. And only after 2 weeks of use, I can see it starting to get dirty.
Honestly, I wouldn’t mind buying one ever couple of month, if that means my car would stay dust free.
