I have the option available but haven't used it since I obtained HEM (where a peep sets up the FT options to save HHs to his/her hard drive to import into the app).
FT will send you an e-Mail when your request is completed, the # of hands their system is compiling determines the wait time (once a job completed < 5 min when I was requesting HHs by date through the beta request).
If you don't already have a poker tracker program (ie: HEM, PT3, etc...) but have plans to obtain or test drive their trial versions...I would recommend setting up your FT options now to save HHs so that you have a decent sample size to review when you do get the app >>>

Save Hand History box. When I tested HEM during the 15-day trial period I happened to have 19K+ hands available to test the app (vs the norm I would have gotten only during the trial period).
