Utilidad de cada tecla y ubicación perfecta. La mejor calculadora gráfica para aprender. A pesar del tiempo transcurrido desde su aparición en el mercado , para mi opinión , no ha sido superada.

Was skeptical to buy a 'renewed' item to start with, however this was a good purchase.Almost new. Everything works great. Came with new batteries too.Happy with the purchase.Product itself was for the kid. Its a known brand and product. People who know how to use can only use it!

I used this calculator in my high school ap calculus class and it has everything and more. For my first year of college, it still has everything I need and so glad I bought it. The case is shiny and not matt which makes it a bit harder to put on but not an inconvience.
