I purchased my TI-83 Plus in 1999 and still have it today. I have never had any problems with it and can only remember changing the batteries 3 or 4 times. I've even dropped it from my 2nd story balcony by accident (more like a friend knocked it off a table on the balcony) and it didn't break. When I turned it on after it fell, my calculations were still on the screen!
It is easy to use and fast enough for all high school and college mathematics.
I'd recommend it to anyone who needs a workhorse of a calculator.Get more detail about Texas Instruments TI-83 Plus Graphing Calculator.
