Works well for quick lens touch ups.
Very great compact tool for cleaning the lens while out and about. It is incredibly easy to loose, so purchasing 2-3 would be wise, its cheap enough to do so.
Very nice tool. Love the all in one solution. I actually prefer this to paper or solution/q-tips. Super easy to use. Takes no room in my gear bag. Won't leak or crumple like paper or solutions may. This one gets my vote!
Alway handy due to its size while doing an excellent job of cleaning without streaks and without liquids
You gotta try this to believe it. It's just magical!
Convenient to carry, easy to use. Works well for both camera lenses and my regular glasses.
I have only used this pen a few times, but it does fine and helps keep the lens clear for a low price
I thought I would need to get a special cloth and a liquid cleaner to remove finger prints from my filters, but this pen did the job. It also has soft bristles on the opposing end for removing dust. I find it's 2-in-1 functionality nice, and it's size convenient. Putting this in my shirt pocket is a better alternative than keeping a clean cloth and cleaner around.
I love this lens pen. It's very effective for fingerprints, etc. Remember to apply enough moisture to the lens/filter first.
