Poor quality of manufacturing
on 10 April 2016
Works perfectly. However, the item I received has the display mounted askew and the plastic convex! Totally unimaginable. To sum up:
1) it was a great instrument ten or so years ago, but now the functionality and display options look elemantary/obsolete.
2) quality of manufacturing is questionable, at least regarding my item. Unrepairable.
3) clearly overpriced, taking into account primitive functions and quality.
The reason to buy is for exams. From my point of view, exam providers could easily present it as a gift, taking into account the price they charge.
