    • Great TI-89
Glad to find a new TI-89, great calculator.

    • Pragmatico
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.

    • TERRIBLE SCREEN!
I bought this calculator for one of my math classes. I saw it was refurbished but cost half the price than a new TI-89, but figured it wouldn't be that bad. However, this is UNUSABLE. The display screen is SO DARK that I can barely see anything! The quality of the screen is so poor, that the words on the screen look like there 2 pixels. This is a terrible calculator, only purchase if you are DESPERATE. ... show more

    • Being a 'renewed' item, it was still almost new and works great
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!

    • Overall the best calculator
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.
