This is something everyone needs for their interior.  I can't stand having dust on my dashboard or console, or even the top of the steering wheel, this takes all of that out of the equation.  A quick swipe of the duster over the hard / soft surfaces of your car and it's completely dust-free.  Definitely worth every penny.  I bought 2 - one for my Mom's car and one for mine.  The price is great, you can sometimes find these in AutoZone or PepBoys but it's going to cost you almost double what Amazon is charging.  After a dusting session, just give it a vigorous shake out your window and slip it back in the case they provide, and you're good to go.
