Been using the NSpire CX for years now, best calculator ever. Just bought this and it’s the same with a few extras, no big deal. If the TI-84, or whatever people use, weren’t taught and used by everyone, so much that they are written into text books, these would be the standard. Cost too much money to rewrite millions of textbooks and retrain everyone though. So, these are a hidden gem. People say it’s difficult to navigate...its menus are identical to a computers menus. Open the menu and you choose which type of math you’re looking for and the options are under that category, “doc” menu has identical options to a Microsoft word document. Really couldn’t get any easier and can’t recommend enough. I mean, it has excel built into it and it even runs rudimentary commands, and you can graph straight from the spreadsheet. I could go on and on, just buy one. Read full review

Amazon was all out of the CX CAS IIs, so I just bought them refurbished here and I got what looks to be a brand-new CX CAS II for only around $40 more than a normal CX CAS. This comes with all the accessories and is, again, in brand-new condition. I haven't used a Nspire before, so I'm still learning how to use it, but at least it's dramatically faster than the 83+ I've been using for all these years. So from a guy that's been using the classic Ti graphing calculators, I will say that the UI is rather atrocious and convoluted. I don't know why Ti just can't keep some of the standard menu buttons to keep navigation simple. I'm sure I'll get better at getting around with this calculator, but for now it's very hard to do anything. The reason I bought this calculator was for the speed, so at least it delivers on that front. Read full review

The pros are the battery last for weeks using it about an hour every other day, it makes math a lot easier, and has many features. The cons are the screen gets dirty quickly, a lot of functions to learn(not a bad thing just takes time), and the touch pad is not easy to guide. Even though it cost more than other calculators, it has made my math homework much easier.
