Summary: Decent pen.
Comment: Not the best I've ever used, but not terrible either. On my camera lenses, even though it does get smudges and spots off, it seems to leave a bit of a residue on the lens surface. It's not terrible, but being picky it still bugs me a bit. I'd recommend it- especially for the price.

Summary: A Lens Pen is MANDATORY for telescope & binocular users!!!!
Comment: This thing is amazing! A friend let me borrow his on a stargazing trip, and I had never heard of one. I had a pair of expensive binoculars I had resigned to having spots and tarnishes on the objective and eyepiece lenses. I of course thought this was some gimmick that my friend had been taken for $10 over. Was I ever wrong! It completely polished all four glass surfaces, rendering them all back to the nice deep purple-green tint I was used to seeing on my brand new binoculars way back when I had bought them. I had tried everything from lens cloths to cotton swabs to get them clean before, and what I thought were permanent disfigurations of either the glass or the light-transmission coatings, they were instantly removed!! My lens surfaces are completely spotless and look brand new. I will never be without a couple of these in my astronomy bag. I hope someone is making several million dollars off this innovation; they deserve it.This is a 5++ Star Rating item.
