Summary: I read the reviews and only saw one person who was truly unhappy with the product. I didn't listen when the review reported that they shipped a broken product, this was a serious mistake. I received a calculator that was about as useful as a $36.00 paper weight they will claim that you can simply send it back, but they fail to mention or consider the amount of time and money wasted on their garbage product.
Summary: I paid for two day shipping because I needed this for an exam since I recently lost mine and it didn't arrive until over a week after my exam was over. The calculator was damaged and wasn't even worth the money. The seller never contacted me to apologize for the extreme delay. Save your money and go to someone else!
Summary: I purchased this item for my statistics at the suggestion of a classmate. Perhaps I have a defected product, but I seem to encounter more error messages than the solutions to problems. Very disappointed.
Summary: The TI calculator company has a monopoly on the calculator business because it is the official calculator of all of the major college entrance exams & others. It's 2012, our cell phones have color, our portable video games are in 3D, but the TI series still has a cabbage green screen and the computing power of the original game boy, all the while costing as much as any new electronic device while being made with 15 year-old technology. It's atrocious.
