The cleaning has been missing for the care of my equipment. The set comes in a blister pack and looks at first sight for the price of neat. The cleaning cloth I have not used since I is one of B & W have here what I use. The bellows with attachable brush has excellent tactile feel. Unpleasant odors or similar I could not tell. The air is pushed properly and punctually through a nozzle and can be relatively easily coarser dirt so blow of lens or sensor. With an attached brush (do not use on the sensor!) Can be easily solved FIXED dirt and then blow away the bellows through the brush. The Lenspen is also good. I had a superior feel expected, the function is not affected and therefore also not bad. The Lenspen is to press from lightweight plastic, with a slider to the very soft brush on one end and an out abschraubaren cap on the other side of the pad is a. The pad is soft, easily removed and reliable streaks and Fingerdatscher on the lenses. The brush can be re-dissolved / removed coarse contaminants. Since it's my first "real" Cleaning Kit for my DSLR, I have no means of comparison, however, would say that this set is worth the money. I am happy.
