Summary: This is an amazing product. I was using another scanner that took forever to get the job done and could scan only one side per scan. This one now does it much,much faster, can scan both sides of a page, and does things like auto-straighten pages and auto delete blank-pages. And being for a Mac, set up was fast and simple. Strongly recommend.

Summary: Having used many scanners overtime - I have to tell you I am impressed and happy with going with your Scan Snap S510M. I have been using it for about a week now and the simplicity of this machine is unbelievable. So far I have not found any problem with this scanner. The two sided scanning has helped with accomplishing my task in a short period of time and I love the fact that it is small and compact.
