I bought the online program last winter. I wasn't looking to build my swing around his methodology per se but I was looking at this more as content to consume while on the elliptical since I can't consume enough golf crap. I approached it open minded and looking to learn a few things and raise my swing mechanics IQ.
I feel like it's worth the money with the amount of content that is provided. It's organized well and flows nicely. It's not one set in stone method either...he has the fundamentals and talks about different matchups for different tendencies. The one thing I don't like is that you must move through the content in the order they have set forth. You can't jump around or ahead to different sections. I think I understand why this is the case...probably better to consume this curriculum with the proper foundations and build on it rather than jumping around and it's also likely to keep people subscribed longer as well. If you want to get to chipping or putting you'll need to plow through swing stuff first and it takes time.
I will likely cancel my subscription when it comes around but it's a very nice product, easy to use, tons of content and easy to manage.
