The calculator works great! Came with batteries but no power cord. :-(. I find it easy to use and use it for college level math classes!

This is a great calculator with a great price.  It is easy for me to use.and is exactly the right size either for my desk or briefcase.  Well made product exactly as described.

A great HP calculator. I have also used at TI-89 but it takes me much longer to do the math, so I returned it for a full refund and bought this HP 50G graphing calculator.

I am happy I purchased another great product from HP! Another satisfied customer.

This calculator is much better than its TI contestants. The display is bright, large and the colors really help visualize graphs efficiently.
The buttons are a joy - large and comfortable.
I have got two of them so far - one for line input and another one for math input.
I love it. I really do.
I hope CASIO develops a product that does 3D graphing. PRIZM 3D? I don't want to use a TI-89.
Thank you CASIO.

I love this calculator.  I'm able to review long logs with dual color for additions and debits to the account.  Easy to use.

Bought this after my TI-84 Plus Silver Edition was stolen. This calculator is just like the TI-84 but instead of having an old school screen, it has a backlit screen. Also it came with rechargeable batteries with charger.
The graphs are colored. Although I have not used those graphs for any classes yet, it may be helpful for students who need to graph in trig and calc.
The only true cons is that it has less memory (though its only 3KB less). Additionally, the calculator did not come with any pre-installed games.... No Block Dude ( 3 )

Tihs is a great calculator for Civil Engineering applications. I really like the RPN function and stack view to see and use previous results with the push of a button. The menus and are very easy to understand onces you find where they are and how to get to them. It really feels and looks good too. I wish HP could desing a calculator like this with nothing but Civil Enginnering tools, no Graphing or things that make the calculator too dificult or crowded. But if you are going to do Enginnering a Hp50G is the way to go.

This calculator has an incredible amount of uses in various math and science work. The many algebraic features (polynomial expansion, factoring, etc.) allow advanced students to save time and allow novice students to check their own work.

The TI-89 also allows students to use several calculus features such as limit analysis, derivatives, and integration just to name a few. Also, the True-Type screen allows the display to be neatly organized without all the clutter and mess of something like a Mathematica readout.

Another nice feature is the plethora of graphing abilities this calculator has. From 2-D, to polar, sequencing, slope fields, and 3-D displays with rotation, the only thing missing from this calculator is a mouse and a printer.

My Daughter needed a graphing calculator for Statistics class.  She is really happy with this calculator.

TI calculators have always been great, but it can be daunting wading through their documentation. This book can get you up and running very quickly, and even helps you to figure out what TI documentation to look at.

I like this calculator very much.  The buttons are a comfortable size as it the overall machine.  I like the large 12 digit display.  Use it almost daily.  To prolong its life I keep it clean and dust free in a draw.  I can strongly recommend it.

I am a junior high math teacher and our school recommends this calculator for students. This calculator does everything a student needs for middle level math. The only thing it does not do is graphing. The price is excellent for this calculator. My students love to use them. It is very user friendly. I would highly recommend this calculator!

The Casio FX-9750GII is a great value in a graphing calculator.  It isn't perfect, but it is a deal for the current price.

The Good:
- Comparable to the TI-83 Plus for about half the price
- Very nice readable 6 line display
- Intimidating at first, but found that I was able to figure out how to do some simple stuff fairly quickly once I got familiar with the menus
- Includes cable to connect two Casio calculators
- Includes a set of financial (time value of money) functions, an unexpected bonus for me.

The Bad:
- The number of functions *is* intimidating at first glace, and the 250+ page manual can be overwhelming
- Not Casio's fault, but since the TI-8x series is so popular is will easier to get help for it at school/work or on the web
- Connection to a computer requires a separate PC-Link cable and software program ($30)
- Curiously lacks a % function (the TI-83 Plus doesn't have this either)

In all I think the Casio FX-9750GII is great calculator and a great deal.  The only reservation I have is for kids who plan to use this for school and/or standardized tests, since so much of the support for these is going to be geared towards TI.

Works great for me. I teach High School Chemistry, and students always need to "borrow" a calculator. This is perfect for 4-function calculators, TI-30, and Casio scientific calculators, but  I wouldn't recommend this for graphing calculator storage.

On par with price/computing power hand-held non-graphing/non-programable calculators. I own several TI calculators including TI-81, TI-36X Solar and TI-89T. Other calculators in my collection include Casio fx-7500g, fx-115 and HP 48G. Looking at taking the PE exam and self-learn courses in engineering and math. Takes a day to go through the booklet examples for every calculator function. Easy peasy!

My favorite non-graphing calculator. If you don't need all the graphing functions or can't use them for a test then this works very well. I use mine quite a bit and find it faster and more intuitive than many others, I especially like the storage functions which take about half as many key presses as a TI.

Works great, and is a handy thing to have at my desk. The calculator is an especially nice feature.
