Agreed. I watched a number of Giardini videos earlier this year prior to my wife's enrolling in Medicare and they were extremely helpful in understanding the plans and policies of Medicare.
I first learned about them from Chuck's Medicare Plan Selection presentation he did for the group last year (November, I think). His instruction on how to use OSHIP rate sheets to make an informed decision on how to evaluate Medigap plans was also terrific. I have attached the PP deck he used; I would recommend reviewing it for anyone that needs to pick a policy for the first time.
FYI - Giardini is based in Michigan but they are a licensed agent for Ohio plans. We used them to enroll my wife in her Medicare policy.
