Customer Reviews:
"I bought a refurbished TI-83 from Topcalcs, and it works great for my college classes. I did not want to buy a new one since Texas Instruments charges too much for an old calculator." - David
"The most durable calculator I've ever had. If you have just one of these calculators, 1 is all you'll ever need provided you don't lose it. You'll likely lose it before it ever breaks. I own one from 7th grade that I have now owned for 15 years." - Lindsey
