Are you talking about the 5DVD box kit?

If, I have only seen short excerpts, which looked brilliant. Leadbetter is very good at explaining things.

And the software that is part of the box is a "Leadbetter-enhanced" version of V1 Golf I believe.
I have the regular V1 golf package (which is only $10 cheaper than the entire Leadbetter box) and find that good value for money.

So if you have use for the software, I definately think this is worth it.
