Top reviews from other countries

1-functionality seems to be the same with fake and real one,
2-Huge difference in clarity of the LCD. The fake one is hopelessly dim/lacking contrast,
3-There is no battery in the battery compartment of the fake one, neither any wire connections/holder contact etc. Just a gaping hole. Obviously with the real one you get the battery sitting there nicely
4-The general built quality of the real one is noticeably much better than the fake one.
5- Last but not least, the price for such a fine machine is unbelievably attractive. Bravo Casio :) Recommend it to everybody wholeheartedly .
