I did one of these through my company years ago. I found it pretty entertaining. Our company was fidelity, so not like it was a creepy place.
DH and I had fun finding the limitations of their calculator with a trained professional :D. Entertaining for all involved, or at least me. DH and I still talk about that meeting, for all kinds or reasons. It's like a deep metaphor or something....
Anyway, once we explained our plan "wow, I want to get out early, but not that early" we were able to have a pretty good talk about possibly using a Roth to help with part of our savings. So, now I have some Roth money to play with, not a bad thing.
He also thought we could use some more international in our portfolio, which was and still is true. I'm not a big fan. Kept it for a bit then sold it. Go big or go home :).
Good to have some outside eyes on the plan. This was also years before I found the forum, so its not like I had other people to really chat with about the nuts and bolts.
