Texas Instruments TI-Nspire CX II Color Graphing Calculator with Student Software (PC/Mac) White 3.54 x 7.48

Perfect item!

Very high quality calculator. Best price among multiple vendors. Relatively easy to use.

Several operations keys: +,-, & enter didnt work, making the unit useless.

Overall a decent product but with all the technology in the world it seems they could develop an easier interface to use.

Mi sobrino la ocupaba p un curso del colegio y era exactamente lo q ocupaba

todo llego en buenas condiciones, y mucho antes de lo estimado. si el envase del producto estaba roto pero el articulo en si mismo estaba en perfecto estado y con todo lo que correspondía al empaque.

Son picked this one due to ease of use

Does everything except make the tea or coffee !!!!!!

The good thing is that it is reliable and seems to work well. Buttons are responsive and are consistent from one to the another. The charge lasts an entire day, however it would be nice to have a battery backup in case the charge wears off during an important exam. The downsides are that the charging cable does not connect direct to a wall outlet, but only to a computer or USB hub. Its also difficult to learn how to use. The up side is that it is allowed for use during the SAT or ACT test and it is clearly a quality product that should last many years. It is required for use in many high school Geometry classes.

I bought this for my son to use for school & that he can use for all his test, ACT, AP, SAT & PSAT. His school issue him a TI 84 plus CE & he tell me that is is very different than his CX II, their input & operation are different. There was a learning curve for him to get use to the CX II but once you learn the operation is was easy to use. The teacher were not able to help him since they are train to use the TI 84. He like it better than TI 84 & it is easier that the TI 84 to input info & formulas.
