Scientific Calculator with Graphic Functions
Bought this for my son's first year of High School. It's is very easy to operate. I had to show him how to use it to do his homework. The battery life is very resilient. This is a very good calculator for the lower price point. There were no other color choices other than black to choose from... but that is completely fine with us (myself & my son).

Flimsy But Works
The casing is thin, the battery cover broke immediately, just taped it up, i am hoping to get 4 school years out of it, so we will see, the price is very good, pink is popular but if you are buying this for a student under the 9th grade i would say no.

A good helper for learning math.
This return is not a product problem I bought the wrong one myself, but the interface of this calculator is as clear as a tutorial, the keys are comfortable, and it is not a matter of effort to knock it out. It is a fact that the calculation speed is amazingly fast, complex operations are solved in seconds, the drawing function is intuitive and clear, and the function image is clear at a glance.

Ok
The overall quality is ok.Cover - The calculator cover doesn’t fit. It’s too big. It falls off which renders it useless. Can’t protect the calculator while in bag.Buttons - The buttons are loose and rattle which give it a cheap feel.Display - the display is ok.Directions - the directions towards how to use functions are quick, hasty, and require a lot of trial and error.Price - Great but it gets you marginal quality.Overall - it gets the job done.

Bought a New calculator, got a used opened torn, dead no papers calculator
I had ordered this as new for my math class, and when it got delivered it was already opened. like someone had clearly opened it I don't even know if it comes with any papers about the calculator or not because this is literally how it came out of the package once I get the calculator out I try to turn it on to see if it works, it doesn't turn on there's batteries in the back already but it does not turn on at all.
