X1 simply does what is supposed to do; flawlessly. I am an attorney and I use X1 several times every day. For instance, I might have written a motion 10 years ago and can remember only some basics, but can search using a few day words and SHAZAMM, X1 finds the document. I might have to terminate my practice if I did not have X1. Seriously -- this is the best program I have, bar none. I had an issue and Chris Wheaton, troubleshooter extraordinaire, quickly evaluated the issue and resolved it. He not only has a deep knowledge of the program, he is a genuinely nice, easy going guy!

X1 makes it so quick and easy searching for an email, regardless of the search term I'm inputting. I like multi color use of different words searched for.

Rapid indexing, easy to customize, fast results, good previewer, highlights search terms, process multiple Outlook PSTs
