Very happy with this purchase. The calculator works and looks brand new. The QUALITY of this calculator is AMAZEING .This is a must have for high school and college students. I have no worries that this calculator will last for many years to come. All the extras that came with it is a plus. We especially love the gel like cover that keeps the calculator from slipping around while you are using it. The color is BEAUTIFUL. I had never seen one like it before.

I purchased this because I wanted to review algebra after decades out of college. When I was in college this kind of calculator was only a science fiction dream. The high tech device back them was the slide rule--which I never fully conquered. I am happy with the purchase. My granddaughter will be taking algebra I in high school this Fall and when she spotted it on my desk she immediately knew what it was and said she may have to buy one if the school does not provide one for free. So it is definitely a must have if you plan to study high school or college level math courses. It is not that easy to work sometimes. I found I needed to purchase the Graphing Calculator Manual by Judith A Penna (I had already owned her Precalculus textbook)to learn how to use this machine to solve textbook problems. Even with this book, some of the functions did not work as predicted. I emailed TI assistance weeks ago and never heard back from them. So I had to figure it out myself. This was a blessing in disguise because it forced me to work at it until I got it right. The machine is much bigger than I thought it would be. I had imagined a cell phone sized item. Its about as big as two phones merged into one.Read full review
Graphic Calculator GOOD CONDI If you are upgrading from a TI-83 Silver calculator, then the transition will be unbelievably easy. In fact, the two calculators are almost identical (with the exception of the 84’s additional features and improved hardware) so you will be able to begin using it almost instantly. The TI-84 Silver was actually designed as an upgrade to its predecessor, the TI-83 Silver, in 2004.
This is a great calculator. I've never used a graphing calculator before but I have to say this has impressed me. The ability to download programs that help with calculation is one of the best features of this phone. I've tried it and it has worked perfectly. So far no problems. I bought this for the price I paid. My math course required a TI-83 or Higher. and the features were better for the same or better price.
This is the most balanced and relaible Graphics Calculator I have ever used. It has the right blend of advanced features inside a robust and reliable package. Sure, you don't have color displays or backlit screens, but the batteries last really long, and you still have advanced computation features. Rock solid and reliable product. Shame they don't make them anymore.
