I took it 2 years ago and I wouldn't recommend anyone taking it. The only good thing that you will get out of it is Kaplan's amount of subject tests and the practice exams. Their practice exams are pretty good, helped give me an idea of how my performance was gonna be before I took the actual DAT. I personally think their review lessons/lectures are completely pointless. In the end it will be up to you to have the motivation to study and prepare for the DAT. By the way, if you do a search in this forum, or the pre-dental forum, you will find that all of the subject tests and practice exams are given for free by several SDN's members.
Good luck with the DAT 🙂
