Mya Mckinney: It’s definitely a calculator! but for my specific class it had little to no use for me :( it was a really cute pink color but it did feel very cheap.

Baking brains and beauty: It’s alittle lightweight and alittle cheaper that i was used to. Also it’s joe solar powered but it was no issue using it ! The pink is so cute and i actually like it !

T. Linz:
The calculator works for what I need at a decent price. Its buttons are able to be read clearly etc and it gives the correct answers.
Just two little things.
1) the actual calculator seems rather flimsy. Like if an average weight adult steps on it they will break the casing which is not brilliant but I use it at home at my desk so no big deal but still -1 star.
2) the supplied batteries came empty. I had to buy new batteries. That happens sometimes regardless of any products price point, so that didn't affect my rating. Was just a minor inconvenience.

Got this out of nostalgic curiosity for the days before use of calculators in schools shunted programmability to top end professional devices. AFAI can make out it is similar to the old Casio fx-6300g kit.
Pleasant for taking me on a trip down memory lane but these days, if you want a programmable device, then I think you're better off getting a top-of-the-line model from one of Casio, HP, Sharp or TI. (I use an HP50g, which beats the pants off this Catiga offering.)
It's minor saving grace is that it's probably the cheapest programmable you can buy.

Marti Rose: Said it is a graphing calculator but cannot figure out how to graph with it. Got many math teachers to try and no one can figure it out

Sara: Wow! What a great deal! I bought these for my high school daughter because I had already gotten the heads up that the expensive TI-83s and TI84s often walk off (aka get stolen), so I read many reviews and looked at all the calculator functions and found these calculators to be an exceptionally good price and well equipped to help her in honors geometry all the way through calculus. I have gone through complex statistics and multi variable calculus and found these calculators to have all the functions needed to help her through high school and college. The graphing function may not be as high tech but often excel is a better options for such needs especially in today’s tech driven world. The bonus is that I won’t have to run out in desperation if she loses one because it comes with a back up and also it is great that she can keep one at hime and one in her backpack for school so she will be accustomed to the use of one calculator instead of switching between brands. The other great part is one calculator did not work and amazon quickly sent another double pack within two days. Amazon you rock! Hope this helps some other parents debating on whether the less...
