I saw this last year at CES and kind of forgot about it. i4u made me remember. For that I thank them. Essentially, it's a little lens cleaner for digital cameras and camera phones. The tip is small enough to get at the smaller lenses. I handed over my cellie at the booth and this thing cleaned off all the gross hairs and stuff quite nicely. Now my cell is all dirty again. Now that I've seen it again, that same urge is back again. I will try to fight it off.
