Amazon Customer: I bought this for my wife because she was taking a calculus class. As it turned out she didn't need it that semester after all and so it didn't get used at all. The next semester came around and she was going to need it so she went to charge it and it just kept display and error message for needing to load software. I did some online checking and it said to reset it. I tried several time to reset with no luck. I went ahead and call Texas Instruments technical support and spoke to a gentlemen. I told him what we were experiencing with the calculator, he told me that it was a voltage issue and to try charging it for at least 8 hours. He said that if that didn't fix it to call back and the battery would have to be replaced. We charged it overnight and it was still doing the same thing so I called back. The individual was super helpful and said that they would send out a replacement battery right away at no charge. Once we received the new battery we charged it for 8 hours and the calculator works perfectly.

Vidya: The calculator is great, my second purchase in 4 years. But the charging cable included is not what is shown on the box. Unfortunately, I bought it in advance of the school year. So it did not get used till a month after, then it did not need charge. By the time I discovered the problem, my window of return was closed. I had a choice of returning it with a restocking fee of $22 or spend $9 on another cable. I chose the latter.
Upset at having to shell out money for no fault of mine

Jorge: The display is a lot nicer than the previous TI 84. The built in apps are also pretty convenient, especially the conics app. Not much changed overall between calculators so it’s easy to pick this one up after becoming accustomed to the TI 83/84, but the subtle upgrades and screen are well appreciated. Battery life is also really good, I never worry about it

Steve: Didn't realize that I needed a calculator to figure up the payments... on the calculator! What ever happened to $10 calculator watches that you could also play football on? Gee whiz! First time I filled out mortgage paperwork for something my kids would carry in their backpack. I told them they better get a good education with it, as that was their college fund and my retirement to pay for the thing.

Jesus G.: Bought this for my little brother because he was taking a calculus class in high school. It arrived really quick, and it was easy to use. Updates are also easy to do and quick as well.
