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

Screen could use an upgrade, but what you get for the prices is nice

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!
