Fully renewed from my old Casio fx250 that I had and accompanied me since my school years (purchased in 1997 for 5000 drachmas), but all things are perishable and eventually give up!
Its plastic is exactly the same, only my old Casio had polished from use, while this one gives me the feeling that it will slip out of my hands.
The keys are nice and have a very nice feeling when typing.
The functions are fully renewed, while it has many additions of statistical nature, but also a new style in the writing of operations. I believe it will last another 25 years. A trustworthy choice and at a very good price!

I don't know how much it will help engineers, mathematicians, etc., but for economic mathematics, it is more than enough. Cheap and good choice.

It brought me back to my student years and the first Casio fx of 1978 then... plus the easy-to-find and replaceable 1.5v aaa battery, the adjustable contrast screen, and the menu that reminds me of the old ones... it doesn't require much adjustment for... old folks like me. A sturdy case that I hope will accompany me for... many years. I liked it!

It requires a little familiarity with its use if you haven't used something similar before, but it does its job just fine.

Good little computer, suitable for scientific use. I use it as an engineer. Of course, the old model I had at the Technical Institute was a dream, but it is no longer available. However, Casio guarantees quality!
