  • Works for me
Color: 991ES PLUS
I am an international student in the US and really struggled using the calculators my department provided to me during exams. I have been using this type of calculator my entire academic journey back in my home country and it is exactly the same as the one I have been using prior to coming to the US. ... show more

  • My honest review
Color: PINK
It’s okay but it could be better, 2 of my buttons were switched around so that was confusing. It works great honestly but I usually have to push the buttons twice to get it to actually work some times. Is it worth it? If you like the color than yes if for the use you can get better for the same price. The accuracy is good if you know how to use the S->D button. ... show more

  • GOT A USED CALCULATOR
Color: PINK
Everything is fine with the calculator itself. The pink is aesthetically pleasing. My issue is that I got a used device. I am not a fan of receiving used devices because I have no idea if it was cleaned and if it have any defects. The packaging was clearly open, the calculator had pieces of whatever on it. ... show more
