The 2ND button is just a shade lighter than the rest. This can present quite an unnecessary source of calculation mistakes. If you use this for hours, you can’t really afford to constantly check if data has been entered correctly. The Professional version doesn’t come with a cover by the way. Whilst BA II Plus Professional certainly looks better and feels more premium, I felt the effort to make it premium (weight and button press) did the calculator a disservice without extra benefits vs the “basic” model: I prefer simple BA II Plus model because: Having tried both thoroughly, I would recommend using the basic BA II Plus model instead of the Professional version. The BA II Plus calculator is used by most CFA exam candidates – but which should you choose? BA II Plus or BA II Plus Professional version?
