My jr. high son uses this in school. After his was damaged we went EVERYWHERE to locate a duplicate- not to be found! Tried a Texas Instrument model- but it lacked a function necessary in school, despite its 'scientific calculator' name. This one is special because it has an attached cover that slides over and completely forms its own hard cover case over the keys, really protects it at school... AMAZON to the rescue! Priced right and delivered to my door.

It's very easy to use, you can master absolutely all options really quickly. I particularly liked the fact that I can choose how many decimal places it will show on the display, the quick and handy deg<->rad conversion and the powerful 2-variable stats mode. It's also quite fast, I've noticed the results pop up sooner than in many similarly priced calculators. ....as a bonus it looks quite cool. I give it 5 stars for sure.

With this calculator finishes my bachelor studies before used casio fx115d very good also but this is but it practices because it is possible to be visualized the data already placed with this calculates the hydraulic structure, electrical and of concrete armed of a habitacional complex of 10 houses.

I have used several different calculators, most of them TIs. This one, in my opinion, is far superior even to the TI graphing calculators. For everything except graphing and business calculations, this calculator offers an intuitive, user-friendly interface to calculate with. Plus, it looks cool: the iMac of the calculator world.

I found this calculator to be an excellent one, my sister uses it in school and she is very pleased with this cheap, but powerful calculator.

I very much like the product. It is easy to understand,desn't take a lot of space,plus design is diferent. It offers all simplest and somewhat difficult mathematical expression in just one spot. However the only item missing to me is the canversion table which is very important on a calculator.
