Functionally, the calculator is great. But I personally have reservations about the physical side, which I' m sorry about because otherwise the calculator would be great. After all, after only 40, the eyes are no longer in the same condition as in the studios (quite a small font, and when the side is lit, a shadow is formed which impairs readability, it is clearly a feature of the display which is otherwise nice). The cover is not very good if you intend to wear the calculator a lot. And the pattern on the front surface, so once again, the design element prevailed over functionality and practicality, because in a certain direction of illumination, it causes the labels on the buttons to be illegible. But if someone does not mind these shortcomings, they will be satisfied with the calculator.
features enough
pleased with the “technical symbols“ function
The “Spreadsheet Editor“ function is fine
Czech is a nice bonus
the display shows in detail and clearly
small font on the display (only “normal“ or even smaller can be set), it is not possible to set a larger font (for ordinary calculations it could be possible to set it twice as large at least for the result) [fx-991ESplus 2nd Edition is beautifully large and easier to read when table lamp lighting]
White color of the cover and lower body (matt silver or matt titanium or simply gray would be more appropriate and practical)
The cover is too bitten and does not protect the calculator very well and is not easy to use. The calculator can suffer a lot when you carry it. (fx-991ESplus 2nd Edition has it much better)
the patterned appearance of the forehead makes the descriptions of the buttons difficult to read when illuminated by a table lamp (fx-991ESplus 2nd Edition does not have this problem)
