I purchased David Bayer's Mindhack program for 500 dollars, and frankly, I would have paid double for it was excellent. I loved it so much that I researched finding a more in depth program and enrolled in the David Bayer Accelerator program for 9,000 dollars.
I regretted this decision the first week of enrollment. Your access to coaching is limited to occasional group calls that are oddly scheduled and run by coaches with very limited ability. You will be enrolled in a low-engagement FB group, have a one hour meeting with a coach and modules. If you voice a problem with the program you will be told to "mindhack" your way into liking the program.
This was my honest experience. It's a promise HIGH deliver LOW model and I honestly feel scammed. Definitely don't recommend.
