    • 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.

    • Did not work when I got it. AVOID this reseller
Calculator works 50% of the time. Sometimes, it just won't turn on. Tried everything, new batteries. Nothing worked. Outside of return window. Very dissatisfied

    • 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!
