I just got one of these for the first time, a lot of threads on here recommend them and they seem like a great idea. Bought a Nikon one from amazon for $8 and while I really like the brush it seems like the cleaner tool isn't really working.
I have a brand new lens that I used for a few days and after wiping off the dust I wanted to remove a little spec of water that had dried on it. When I use the cleaning tip end it didn't really do anything, so I fogged it up by breathing on the lens, still not much result but better. It seems like I was just using a micro fiber cloth without any cleaning solution. I tried breathing on it again and accidentally touched it with my lip (hehe) so now I had a larger mark to remove.
I kept using the cleaning pen, putting it into the cap and twisting to get the cleaning compound, and in the end I feel like it required way to much rubbing to get clean. And still when I look at in under a light at the right angle there are still spots where it seems the smudges were thinned out and wiped around until you couldn't see them anymore.
I also tried it some on my camera's LCD screen that had some big oily fingerprints and it was definitely just moving and spreading the prints around.
Should I be thrilled by this pen and see it remove fingerprints fairly effortlessly?
