Summary: This calculator arrived as stated but did not meet my expectations. I expected the calculator to be relatively free of defects OR to at least have obvious ones noted in the description. Pixels on the calculator are non-functional. (Pixels may be the wrong term though.) Basically, when I attempt to pull up the constants screen which lists constants at the very bottom of the screen, the bottom portion of the constants menu is cut off making it hard to discern what you are...
Summary: The calculator was what I expected. Definitely used but in good working condition. Seller even included a new set of batteries because the ones in it were almost dead. Not sure if that's a common thing but it was nice. Also, it came with the CD for the TI-86.
Summary: I have used the TI-83, TI-89, and the TI-86. The 86 is my favorite. I like the layout and menu structure. The particular reason I really enjoy this calculator is the placement of the "EE" button. If you are using this for engineering and science problems the EE function being it's own button (not a "2nd" button) and being placed convieniently above the number pad made the calculator very easy to used for science/engineering problems. Highly recommend!
the product is very clunky, hard to use, bad display.

Summary: Bought it for High School Student, and I can not believe the price is not cheaper than smart phone which can accomplish the same calculator functionality or better. Because of the school requirement, I was forced to purchase a graphic calculator. Features are out of date (like 90's), black & white LCD screen, and keys are very clunky.
Summary: I haven't had to use a graphing calculator in a long time, but this one works perfectly. The best review for a product: It works as intended and you will be hard pressed to find something wrong.
