Texas Instruments TI-Nspire CX II CAS Color Graphing Calculator with Student Software (PC/Mac)

Works perfect for our needs

First, it arrived quickly and in very good condition. Besides the manufacturers package (with the manuals and an USB cable) it was also sent in a bigger box with plastic airbags, so it was very good protected. Regarding the calculators performance, so far very good. I used to have the first nspire CAS, and this one is faster from the beggining, it boots faster than the old one. I got this one as replacement for the old one (I had an accident with a cup of coffee) and I will test it further in the next days but so far very happy.

I was contemplating spending a lot of money on a calculator but I’m glad I did! It’s easy to use and I can tell it will be of good use for me in calculus

Definitely like night and day compared to the old TI I had

The calculator itself is great but the navigation is just not user friendly. I feel the need to try and make the navigator like a laptops trackpad has ruined this calculator for me. It takes me multiple try’s just to click on something since the sensor for the navigation is poorly done. If the interface was done better this would be the best calculator by far but because of this I find it more efficient just to use my TI-89 titanium.

Llegó en buenas condiciones . Buen producto.

I’m a senior citizen who received a large portion of my education before calculators were invented. It was all slide rules and tables of logarithms. This device is utterly amazing. Texas Instruments in Australia have produced many useful YouTube videos that collectively demonstrate everything the calculator does. It will take a lot of practice to become proficient but that’s the fun part.

It is a great calculator and was a good improvement over my ti-84 that I had for a few years. If you have previously used calculators with graphing functionality and are they type of person who likes to pick through the settings It is very easy to get used to. Depending on if I remember to turn it off when I am done I can get it to last around 2 weeks on a single charge and despite the long lasting battery processing speed on this calculator is much better then ones I have previously used. I am currently an engineering student and having a good calculator can make a huge difference in ones studies.

Im an adult engineering professional, not a student. Really like the CAS system that solves, simplifies, factors, expands, etc. algebraic expressions. No need to convert systems of equations to matrices. No worrying about silly mistakes in algebra. I really like that expressions can be variables, makes substitution super easy. Im coming from a TI-82 (it still works!) so I felt fairly comfortable, but still had to watch a few YouTube videos to get the gist of documents and an overview of the features. Read the manuals, watch videos, google, etc and the fun and power slowly reveals itself. I installed the software, calculator comes with a license but you have to download from TIs site. Used the software to upgrade the firmware to latest version no problem, transfer files to and from calculator, and the software emulates the calculator so you can use your computer for editing, screen sharing, etc. All very cool. Build seems solid, though not as rugged feeling as my old TI-82 which is built like a tank and survived many drops and abuse. Bought a padded case for this one, which I dont think is needed for the older models.

This is practically a cheat code computer in your pocket.
