I cannot compare it with other card scanners: it is my first. But it is a very efficient, and accurate tool for all of us for which networking is an essential part of our business. In a moment you have all the data of almost any business card transferred to your computer. There are sometimes small corrections to do- and an easy software is there to help you to do it. But that is the exception, not the rule.
An even better link with Outlook would help. You can easily export everything to Outlook, it is true, but in principle they promote their own specific contact management software, which doesn't make much sense to me and I guess to many others.
So, positive evaluation as a wole.
