Summary: Great for cleaning tiny lenses like those on smaller pocket-sized point and shoots. Very portable. I keep one in my point and shoot case all the time. LensPen is a proven solution for cleaning optics, this just makes it more convenient and versatile.
Summary: I was always so worried about the smudges on my lens and so frustrated with myself for constantly bumping it until I got this and no I'm just VERY careful to get all the dust off the lens before using this amazing pen. It also has a little brush on the other end which I find useful on the whole camera when dust gets in the tiny spots.
