I used this to scan thousands of photos into a database -  and it did a fine job.  Occasionally the rollers would loose tack and I'd have to clean them.  Kodak makes a special cleaning solution for these rollers but I never bought or tried it.  You'll have to download the kodak scanner suite software for PC to get it working properly.  Comes with the unit, feeder, a/c adapter and nothing else.  Lots of info on the internet on how to optimize using this device.
