Does its job to remove dust deposited on my SONY NEX6 sensor. Safe rubber tip for clumsiness when cleaning. By cons consuming unpacking; the product is packaged in a plastic shell welded closest to the product; you have to play with a small pair of scissors to cut size packaging around the product (going to a few millimeters of the product with the tool on all the contour ... not very study all that). Another small inconvenience ... the smell. Upon unpacking it feels to be in a local tire store.
