Unfortunately the HP 4050 purchased through Amazon was damaged in shipment. Processing of refund was smooth, but slow because of UPS intermediate process. Rather than try another shipment I went to a local source and found that they had the 4050 on closeout. So I got it for $50 less than it would have been through the Amazon source.The scanner itself seems to work as advertised. Instructions and manuals are very sketchy, but I have been able to muddle through. Sometimes cold restarts are required if false starts or changes are made during process. Processing of 16 slides at a time is slow, especially if multiple processes such as cleanup and color correction are requested. But the time it takes to catalog and add metadata for the images is similar to the processing time, so can go on concurrently for the previous set and no time is 'lost'.I didn't need the HP photo storage and organizing software automatically provided.
