one word: EXCELLENT .... I had some dust (about ten in a year, I am very careful when I change targets and can also be three or four oil stains that had arisen from the use My NIKON MICRO 105mm f2.8) on my NIKON D7100 sensor. One pass and everything is gone, my sensor is like new, and it did not take me more than 10 minutes, with a can of apprehensions but is now completely reassured about the use, next time will take me 5 minutes max. This product is excellent .... I find that no one speaks enough, it is a miracle product, super easy to use, safe for the sensor (no friction, and we put it raises) ... PENTAX ; NIKON; CANON or apparently has long used this product after assembly line on sensor devices after a final check before packing (dust is everywhere). I recommend this product 100%.
