Great Product! Very easy to use. Awesome Functionality.
This is one of the best education investments that i have ever made. Very happy with the purchase. The Calculator is simply great. I understand that in North America teachers and books only uses TI Calculators because is the tool that they have been using for years. Otherwise here in South America most of the High Schools/Universities uses Casio. I use to work with a Casio Graphing FX-7400 for 7 years and was really happy with it. Like my old Casio this new also do the graphing but it does twice as fast!. The FX-9860 Gii is a beast!!. Super fast calculations. The fact that comes with screen light are really nice!. Love the fact that come with 4 size AAA batteries so there is no need to recharge every week like TI or HP color screen calculators. I highly recommend it. Great Price Great Value. Thank you to Casio for the great work building this beast!.
