Good calculator but quite expensive for students
It is quite expensive for students to buy but the quality might be good investing in. The buttons don't make any clicking noise.

Excelente calculadora científica
Ótima calculadora científica, de qualidade. Esta versão sem o LA (creio que seja de Latin America), não possui idioma português, somente inglês. Comprei já sabendo disso e pra mim, tudo tranquilo.
