    Great Calculator, Given you know how to use them.

    A really great calculator at a really great price. I bought a refurbished calculator and it works works 100%. Came with batteries, you can download the manual from TI website. Link cable is not included (although it is still shown in picture), description does mentions it does not come with it. The design and software in this calculator is not very user friendly. Some training is required to perform some calculations if you are a first time user. The display in these calculators do not have a back light, meaning you need a external source of light (such as room light) to see the screen. This calculator comes with many features, it is perfect for college students taking calculus, statistics, or other advanced mathematical courses.

    Great buy!

    This was required by my grandsons high school and with 3 teens school supplies & clothes add up quickly. This is over $100 brand new and so we saved a lot of money buying a gently used one. Thank you!

    Good as Calc

    Great calculator and in excellent condition. Had to factory reset it to find settings but wasn't a big deal. Made systems of equations questions for statics really easy

    Amazing Calculator!

    I am back in college and am using this calculator for my Chem 121 class, it is way better than my old casio. Came in great conditions, does not even look like it was used at all.

    Great quality-user friendly

    It's in great condition and arrived on time. I bought it for my niece. She's been using a much older version and this version has made math life much better for her.

    Great price

    Outside of calculator was heavily scratched, didn't ship with batteries which was a big disappointment, and some of the text on the menus doesn't fully load but the calculator is still fully usable. For the price though I think it was definitely worth it, and it shipped promptly.
