    • Not too bad
It was a bit difficult to use at first, and I had to look up a few of the buttons online. The Amazon brand batteries it came with didn't last a full college semester either, so that was a bit interesting when I had my Stats Final, but luckily I always carry a back up calculator. The screen is a bit dark as well, but hey, it's a calculator and it definitely calculates! ... show more

    • very well treated calculator
For 35 bucks for absolutely no blemishes and a perfect screen is more than I asked for! Calculator is great for calculus and compared to the price of new calculators I couldn't be more happy!

    • Screen froze not even 1 hour in
I used the product for roughly 30 minutes to finish homework, at that point, the screen froze and has since been stuck, removing the batteries did nothing, just turn the screen off, it was still stuck when the batteries were put back in. The only solution I found was taking out both the batteries and backup and letting them sit for a couple of minutes, but when it became unstuck, the screen froze not even 5 minutes later. The seller was very helpful with the whole ordeal though. ... show more

    • Don’t forget to order the special battery!
Standard TI calculator and highly recommended by engineers. Be sure to order 1A batteries with this because they are hard to find in stores.
