    • Being a 'renewed' item, it was still almost new and works great
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!

    • Overall the best calculator
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.

    • Device wouldn't turn on, needed some extra work.
The PCB contacts for the battery carriage were worn out so the calculator would not turn on. I had to disassemble the calculator, clean the pads, and reposition the contacts in order to get it to work. Something this obvious should be caught before sending out a unit as "refurbished" Once fixed the calculator works as intended ... show more

    • The calculator did not work.
The calculator was received on time but did not work. It looked like over used by someone. I received it today and returning it right away and have ordered the same calculator from another vendor.
