I used to see these dusters being used often at various car shows over the years.
Especially when they were all the rage/craze when they 1st came out.
But most of those very same owners I heard from later on, said that they were NOT using them any longer, due to the resulting damage done to their finishes.
Now I can't readily say if that was due to user error, or the product itself. Suffice to say that nowadays, I very rarely see them in use.
Make your own deduction based upon that.
