I find it has a really clunky interface - like something from the Windows 3.1 days. Another thing I don't like is, say you enter a four-character term: it only (as far as I know) searches for the entire term, and doesn't look for other terms starting with one or more of those characters. Dr. Eye does look up these partial terms.
But for sheer volume of terminology, Wenlin can't be beat. I use it all the time, and I'm constantly adding vocab I find in it into Dr. Eye - my primary translation tool.
The insane amount they charge for it isn't justifiable in my opinion, however. It doesn't surprise me one bit that it's been pirated.
