It is strange that I am asked my opinion on this unit when I returned !! Dust collects on the ice inaccessible scanner, e that is large enough since it can scan 10x15. So I was afraid of this sealing problem on a large area, and I changed Rollei PDF-S for 290 which only slides and negatives. Results are means of slides and negatives, but this is compensated by the speed. The Magic Touch is not used much and increases the time with 30 making it lose its interest in this type of scanner (which actually made a picture and does not scan or speed of!). By cons on photo paper the result is worse than a flatbed scanner, it's also why I traded!
