I thought DIT was a waste of money. Way too much information for what is needed on the APMLE. Many of of the lectures are not even on the APMLE so you just end up skipping them. I stopped after a week and just buried myself into FA. Maybe if you used it just for the high yield topics is would be good, but just going through everything was way too much.
With that being said, I did have a buddy who really liked it. Depends on your learning style I guess.
