I like the colour I chose. It is very light so it seems to be something you might need to take great care it doesn't fall. So far it works well and is accurate. It is relatively easy to use and the digits are readable both on screen and on the keys.

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.

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.
