Unless I get a better functioning replacement

Aliyah K. Hickman, Amazon

  • Summary: Everything looked okay at the start. It arrived on time. As soon as I started to use this calculator most of the functions were not accessible. They look gritty and distorted so that you can not read them. If you tried to use the functions and buttons anyway they don't work. Unless I get a better functioning replacement, I'd like my money back and will gladly return the item. Never purchasing from them again.

Horrible

  • Summary: This calculator is a mess. The sender said he/she used it for one semester but coming to fine out it was a lie. How can you use a calculator for one semester sell it and the buy experience nothing but problem with it? The calculator shut down on you in the middle of a problem. I will advice any or everybody not to buy a used calculator ever.

  • Excerpt: This calculator is very nice. I reccomend this a lot when you have to buy the calculator. This has all the funny and exciting functions and options we can press advantage. Differently from others, this can be used for calculus and other mathmtical subjects. I haven't used this a lot yet, but I am expecting them a lot : ) Untill now, I've used this for lots of calculations and graphing something! I really recommend you this a lot.

Less durable than much cheaper, no-name calculators

A.D. Martini, Amazon
4 March 2015
  • Summary: This calculator lasted through only four months of routine use. The refund/replace period ended after two and a half months. For $133, and from Texas Instruments, I expected a much more durable product.

Calculator for College

Sandy B, Staples
12 February 2015
  • Excerpt: I checked several stores for pricing on this particular graphing calculator by Texas Instruments and Staples actually had the best price. I just recently started ordering from Staples, mostly because we don't have one locally and hadn't thought about shopping online, but I'm certainly glad I did! Not only did I save time and gas shopping for this calculator, I was able to have it delivered to my door the very next day.
