Summary: My boyfriend has a weird hobby, which is collecting calculators (he LOVES math). So this calculator was one of two gifts that he requested for Christmas, and now he takes it with him where ever he goes (i.e. school or shopping). He just completely LOVES this calculator.
Summary: Graphing calculators are finally coming around with a balance of good looks and a cleaner user interface. I'm very sensitive when it comes to my eyes. This Casio screen has backlighting - finally a calculator I can clearly see. The high definition screen makes the numbers and lines look very smooth. I wish that HP would reinvent themselves when it comes to the calculator display. The Class Pad II is fun to us, the equations and corresponding graphs are color coded.
Summary: I ordered the package on a friday. Monday afternoon it was in front of my door. Amazing calculator, pretty fast too. Contact support (online) during delivery for tracking was definitely a 10/10. Condition of the calculator was fine. I recomend this type of calculator specialy for students at University or lower. Many functions and it's simple and smooth.
Summary: I have been a Texas Instruments and HP user for years and never dreamed I would leave my TI-Nspire CX CAS for a different calculator. I am a Computer Engineer and Civil Engineer and working on a Masters is Electrical Engineering and this calculator is really EVERYTHING anyone could ever need for any discipline. I have created several eActivities that help me with the equations that I use every day.
Summary: The screen has a low contrast, shows glare from nearby lights ridiculously easily, is hard to register the pen accurately,... and finally.....Ta Da! It just died after sitting on a shelf for about 10 months. Toast. Trash. A little research shows that mine is not the only one that died in this manner. When it worked, it was hard to see.
MUCH better options at slightly to MUCH lower pricepoints...

Summary: It's relatively expensive for it's hardware. CAS in limited testing so far is at best passable. I'll keep hacking away at it for a while until I either give up and store it or Casio releases some firmware that REALLY helps at least the sw side along. (Kinda busy as I also purchased an HP Prime and am MUCH more interested in getting that going than this, and further distracted by the fact that I also bought Amazon's Vita bundle deal plus a rather large RPG...
Summary: The Casio FX-CP400 is wonderful. It is a huge upgrade of the Casio Classpad 330 Plus. Looking at the two calculator models together is like looking at 1950s black and white TV next to HDTV. This calculator is a bargain!
