Good Calculator--too much of a monopoly and price gauging
Reviewed in the United States on November 9, 2017
I bought a refurbished TI-83 from a third-party seller, 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 technology calculator. They have a large monopoly for students who go to grade schools and colleges. Since many schools require their students to buy them, they are making a killing in profits while the calculator costs only $20 or so to make. Most cell phones can do the same thing at faster speeds, but most schools don't let students use them on exams to prevent cheating. I wonder why the Federal Trade Commission doesn't stop TI's monopoly on their calculators? I do like my unit, but I wish they weren't so expensive since this technology has been used since 80s.
