Pros: The double-feed prevention roller does an excellent job, which is the reason I bought this scanner. Handles thin and glossy paper (textbook pages) very well compared to HP7800.

Cons: Scan quality is poor due to stupid design. Plastic window over scan element is statically charged, so picks up paper dust which rapidly degrades image quality. Concave shape ensures it stays on the window, forcing frequent cleanings. (The HP7800 uses flat glass, which is basically self-cleaning as pages are pulled across it.) The dust also gets behind the window, which is even harder to clean.

Overall Review: Quick Scan software which comes with it is demo version only (30 launches), which works very well but costs over $1000 for full license. Drivers are quite annoying with their service requests, which have to be reset through separate utility. For the price, I expected more, so now shopping for a scanner which feeds as well as this one but has better quality results.
