    Surprised, the delivery was very timely. I like this calculator very much. It is small and easy to carry, and the calculation is accurate, and the battery capacity is also very sufficient. I am very satisfied with this shopping.

    This product says “new”, yet box is damaged and goods inside were obviously handled because you see someone’s greasy fingerprints on the case. Not happy beingbthat this was supposed to be a gift😡

    I've had this for a few days and so far I'm very satisfied with the calculator. It's like a dream that a seemingly quite powerful calculator is paired with competent directions. I haven't tried all the features yet but it has me looking back on matrices and differentiation, integration, combinations and permutations. It leads you down the garden path to understanding applied math. Looking into it, I didn't know complex numbers is just math incorporating the square root of a negative numbers. With tools for students as well as professionals. I'm surprised it didn't have a digital logic feature. A nice gift to myself for a fist full of quarters.
