Texas Instruments TI-84 PLUS CE Graphing Calculator, Black (Frustration-Free Packaging) (84PLCE/PWB/2L1/A)

Dura muchisimo la bateria, excelente calculadora.

Clearly a refurbished unit, it had scratches all over, even when I paid for a brand new. I was thinking about getting it replaced but honestly I just want my money back. Definitely not worth it.

Best calc ever

We bought two for high school to go with them through college and beyond. They say the battery last and it is extremely easy to use. Teens highly recommend .

It’s great

This calculator is easy to use with a good display. It works great for calculus and other upper level math classes.

My daughter needed it for her class..

I was happy to receive this calculator in great condition as a used item from the company Exec Concepts but was VERY DISAPPOINTED that there was no charging cable included in the package! Exec Concepts, how am I supposed to charge the rechargeable battery in this calculator if you do not include the cable! It should MOST DEFINITELY come with the calculator.

Quick and easy shipping. Meets my expectations and is easy to use in conjunction with college algebra.

Bought two of these for my kids at $150 a pop. One came cut open at the top... not happy about this. Hoping that it works and wasn’t repackaged and used. Only time will tell. But at that price tag and expecting brand new I expect my item to come fully enclosed in its packaging. Mind you this packaging is not easy to open. Therefore, it looks as though it was cut open.
