While it seems like a great idea, I was very disappointed in it's actual performance. The brush is a great idea although I already have several of them in my camera bags. The other end that is supposed to remove smudges and fingerprints proved to be just about useless in my opinion.After 'cleaning' two filters with the Nikon Lens Pen, I used a micro fiber cloth to actually get the smudges and film off both sides of the filters.As far as I'm concerned it's not even worth giving away as stocking stuffer.
