Do not purchase this item. I purchased this item after many hours of research on different types of photo scanners. It received high ratings but I can't figure out why. The program was difficult to install (took five installs before it finally installed correctly) and then to even get the scanner to work properly was a joke. And did I mention how unhelpful the instruction book is? I have over 400 slides to scan and at the rate of time it takes to scan, I will still be scanning this time next year. I am very disappointed.
