    • 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!

    • 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 Noticeable Defect in Screen :-(
Review Image by Alex F
"Renewed" calculator was pretty nice except for a very noticeable defect in several pixels near the middle of the screen. I'm glad that I had time to buy another and return it before it is needed. Clearly the renewers need to do a better job.
