    Fabulous!

    love it..... its very light weight & slim. Build quality is also very nice. For beginners I prefer you to use the manual for knowing all the features. The manual is also easy to understand. If you want to use the bar code properly download Casio edu+ application to view the results on your mobile.

    Simply awesome

    The screen is really nice and easy to read, probably about the best I've seen without a backlight. I've used it in some pretty dim lighting and didn't have to strain to read the screen. The buttons are quite sensitive and I have to be careful not to accidentally enter things. If you just brush the keys they will often times be activated, so I think the keys could definitely be improved upon, but it's a minor gripe.

    Best Calculator I've used!

    This is a great calculator. I actually used this exact model that my friend had before I bought online, but was still taken aback by how beautiful it looks.
    A lot of functions are available and there are lots of YouTube videos too describing the features, so definitely check them out before buying.
    Other than that, as a buyer, totally recommended!
