I have, twice, at ten year intervals. You have to be specific about what you're looking for. Me, I was looking at a change in careers and wanted advice into what other jobs I could look for with the skills I had at the time.
It was interesting to do the tests and finding what kind of work my interests lined up with, and which I had good aptitudes for, but that's basically all I learned. Practical knowledge or advice that would steer me towards making that change, zip. Final recommendations were to go back to school for more training, which I knew already but couldn't be undertaken.
In the end, I got better help from a psychologist I was consulting with on a different matter not long after. He digged at the reasons why I was unhappy in my job, and it wasn't what I was doing, but the people I worked for that were the problem.
