Fairly easy to operate, this particular one has an attractive color, is programable with TI basic, Easy to read display, Connects with TI education app downloads and support. If you are a student bring an extra set of batteries with you as it goes through them fairly fast...I am using rechargeable nimh type...(probably not as long lasting as regular AAA type).No color display is disappointing but not a deal breaker. Not a pocket calculator.

Product as expected except it had been well used with some scratches on screen and roughed up front. However, I only needed it for one last class so as long as I could see answers and it worked plus getting it drastically reduced was a great deal.It was exactly what I had in mind. Thanks!

This is the best drop light I have ever bought. It does not blind you or burn you and it is light weight. I did not like the design of the hanger in the picture and just figured I would make my own. When I tried it the hanger works perfect. It's better than regular ones. Great light.

It doesn't work, I tried to use for mathematics for my son who is in middle school. Many calculations are giving error for instance solving the quadratic equation says it's an error. He uses similar model at school where he can work on the same problem.

Has all the functions you may need for HS and college courses. It is an old design, though, does not have a color screen or anything fancy. However, it is built Texas tough :)
