This is one of four manuals I have downloaded recently.
Purchase was very straight forward and the authorising email arrived in about 4 hours.
The quality of the scan is good. Print is clear and square to the page edges.
Exactly as advertized. High quality digital copy of the Nak 610 user manual. Easy download and access. Highly recommended.
