Customer Review

Probably the best and most distinctive feature of this calculator: The display that functions written down as I on my list! No more long lines in the calculators, where you would never find a mistake, because the chaos would be too big! Everything is presented perfectly!

But exactly poses a small problem in itself: With a little more difficult representations (eg: root of a fraction) is the calculator slower. So one has to be careful that the calculator any typed numbers "swallowed" when you type them too quickly.

Conclusion: Super calculator with an infinite number of functions, but slightly more complex functions to its knees!
