Solid, but the display holds too few digits and very slowly

Casio FX-991DE Plus technical and scientific calculator with natural display (Office supplies & stationery)

Customer Review

I have the calculator has been going for about 2 years. Viewed holistically, it is a solid calculator with a bunch of features for less money. For 20 euros you get a good package mathematics. Processing I also okay, for the price you should not expect too much flat.

But what bothers me very, is the partly lame entering. Typing too fast, so it may be that the calculator "swallowed" a few paragraphs, because it does not come with the graph behind. Especially when you type fractions (ie those inputs that a little Challenging look in the display), the Casio lags tremendously. This is very annoying, as it so often happens to me that I again have to look over the results and inputs over it. In an exam, in time are really points, which is fatal. Had Casio installed a strengthening processor in the box, the problem in my opinion, were not present.
Also reminds me negatively that the display holds very little digits. Are you a long bills, so you will quickly reach the limit. That's not bad for a capital value of 8 periods, as you can well this "disconnect". In an equation, however, is complex, and can not be easily separated, which is also fatal.

CONCLUSION: I recommend this computer is very limited. For the school it is certainly perfect and covers all functions. The problem of digits limitation falls only little weight. The problem of lame input is also here.
Not I can recommend this computer for the study. Just when the equations are something more complex, so one often encounters the problem that the Casio holds little digits. The lame input annoying huge. I am studying business administration and would not buy me this calculator for study.

POSITIVE:
- Many functions for little money
NEGATIVE:
- Display summarizes enough digits
- Calculators often paralyzes (-> will not perceived)
