Who wants to clean only dust and lint from its sensor, here gets a first-class instrument. The soft top is triangular shaped to also clean corners. Lifts dust in my opinion in the pad of the tip and not only pushed aside. The pen is solid, the angle tip practical to come to the last corner. It is about the size of a ballpoint pen, so fits in anywhere. The pen is not recommended for surface cleaning and greasy dirt or surface films on the sensor, I mean.
The price is whether the lack of competition justified, however, in absolute terms, greatly exaggerated for such a plastic part made in China. Material value is felt 10 Cent.
Nevertheless, because of the good function 5 Stars.
