Because the first tip was deformed (locally bent too much), it was replaced. As for replacement correspondence it was smooth and re-shipping was also fast, but the thing that was sent for the second time was locally bent. It is a product which is incomplete although I think that it is due to high class grade, the final process is hand grinding, and adjustment by grinding. There may be difficulties in quality control of Kokuyo.
As soon as I started using it, the rubber packing of the pointing part went off and the usability became worse. It seems that it will be hard to return to the original once you go out. Well made of china? It is a feeling.
