When I first got my V850 the holder could draw dust from 10 feet across the room. Well, almost that far it seemed. It was a real pain for sure, but the more I used them the better they seemed to get. I think they are really electrically charged for the factory production process and with use this static charge is discharged. At least a little anyway. I have glass carriers for my Nikon LS-8000 and they sure don't seem to draw in dust like the ones from Epson. Still, if I were to scan for a special shot I wanted hanging on my wall, I would wet-mount for sure.
