Has anyone had any experience with Ebsco's Ebook Academic Collection?  I am particularly interested to see what the users experience has been and whether it get used enough to warrant the investment. 

I am also interested in its searching features.  From what I have gathered, content can be displayed down to the chapter level.  Can searching be done at the chapter level as well (ie: search terms that appear in the chapter title, or searching on the chapter level by subject?

Any impression you have of the product would be useful.
