The unit fits and works fine, but I have some quibbles.
a) Give the size of the scanning area, they could have increased the number 35mm negative images that could be scanned at one time by redesigning the carrier.
b) Slide film carrier would have been nice.
NOTE: Epson stopped making windows drivers for the scanner , so this is only good if you have an existing Perfection Scanner with software that works on your current machine/OS You can buy vuescan but that's $80 - which is approx. the price of a basic new scanner with 35mm capabilities (ie Cannon LiDE 120) that has higher resolution and OS support.
