Texas Instuments TI-83 Rocks!
The TI-83 is capable of so many math calculations I could never master them all. It is great for algebra, trig, calculus, and much more. Great for students. The price for pre-owned calculators is low. I recommend it if you need this type of calculator.

Complete Disappointment
What I cannot say, for sure, is whether my disappointment stems from receiving a more-used-than-claimed item, or if it's the item's quality, in general. We had it for less than a month; the display went completely bad. I've since learned that this seems to be the case with others who have purchased this calculator.

Nice calculator!
I received the TI 85 calculator today for my son who is in high school. We put in brand new batteries but we can hardly see the numbers on the screen it’s so dark. After looking at a YouTube, I was able to lighten the screen. Good calculator. My son and I are satisfied!

Display Screen
The display screen is not designed correctly. It is extremely hard to see. Very dim. The color of the numbers and the screen are almost the same color. TI-85 Calculator is a waste of money. Find a different brand.

TI-85
Received fast and well-packaged! Son is using it for college and so far all works great. As expected a tiny bit of wear (used item), which is why I gave it a 4.

TI-85? Best calculator I ever had.
This is the One True Calculator. You can load assembly programs on to it via a serial cable. Playing Tetris during math class in high school was the bee's knees. Buy one now and experience some of your very own 90s nostalgia.
