5.0 out of 5 stars Overall the best calculator
Reviewed in the United States on October 10, 2022
I used this calculator in my high school ap calculus class and it has everything and more. For my first year of college, it still has everything I need and so glad I bought it. The case is shiny and not matt which makes it a bit harder to put on but not an inconvience.

5.0 out of 5 stars Being a 'renewed' item, it was still almost new and works great
Reviewed in the United States on December 28, 2022
Was skeptical to buy a 'renewed' item to start with, however this was a good purchase.
Almost new. Everything works great. Came with new batteries too.
Happy with the purchase.
Product itself was for the kid. Its a known brand and product. People who know how to use can only use it!

I had purchased another brand of calculator for my high school student and she struggled with it as did her teachers, they recommended this one and it works perfect.
