Good quality

After being ripped off by Banggood, which sent me a fake first edition of this calculator, I purchased this one from Amazon / Casio. When you have the real thing vs the fake one you see the difference.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 nicely4-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 .

A very good product
