My job was to digitize all slides from the past (years or decades), what would have been an ordinary flatbed scanner a "never ending story". The device was unpacked quickly and turned on but the menu took me about 10 minutes and then have a look at the manual. After I understood the operation, I put also going the same and it was really extremely fast progress. Included are two adapters for framed and unframed slides / negatives. I chose the version with storage on SD card and scanned a magazine after another, that went really fast progress and in a good half a day I was with all the old slide and negative cases by. (6 case with mounted slides and hundreds of negatives)
I can really recommend the device each and one also needs to digitize a computer because you can scan directly to an SD card.
