Summary: this is a very nice product indeed. i just received it and updated the OS to the new version which added 3D and other functionalities that i did not test yet. the 3D plots are excellent and are great quality, I'm impressed.
I love this calculator and it is well work the money

Summary: I love this calculator and it is well work the money!!!! Used for College Algebra and Statistics courses. It was great to be able to enter the problems just as they appear without having to learn a calculator input method....
Summary: Big , bulky. heavy, outdated look! Keys feels very cheap. This thing is so heavy that 10 minutes in your hands, and you will be tired. Display usage not well designed. For example, you enter an equation , it prints the result in another line.
