    I spent weeks trying to decide where to purchase the calculator for school, after days of online searching and browsing, I went into the Crestwood BestBuy and received kind greetings and talked to employees who really knew what they were talking about. I am very pleased with the experience!

    This calculator is nice. I bought it because I thought it was a must for my major (Electrical Engineering), It was very helpful, but honestly, there are so many free calculators online (such as Symbolab, Desmos, Symbolab) that it did not seem at all necessary. Now, I am just a freshman so it might become useful in the future, but not necessary now. It is easy to use and there are many useful tools, so it is not a bad product. That was just my experience.

    My daughter uses it daily for almost 2 years. It would be my go to as well if I had to purchase another one. It has all the functions needed for calculus and engineering courses. The choice is yours but this tool works well and some of my colleagues would swear by it as well

    Functional and easier than the HP. Some lower level classes will not let you use this, but in Circuits they do allow its use.

    My son needed it for his high school and had been using it since it was brought. No issues. It also has slide in cover to close when not in use. Saves the lcd screen from all scratches when not in use and from all his books in the bag.

    This calculator does it all. It can do integrals, derivates, matrices, and a bunch of other stuff that I haven't learned yet. Make sure you download the read the getting started material from TI online
