Summary: A very nice calculator. Feels well built, and always adds the numbers correctly, even if I put the wrong ones in... Just kidding about that last part. My only complaint is that the case is very cheap vinyl. It cracked after a couple of weeks. I picked this particular one because of the case, so I could travel with it, without having to worry about it breaking.
Summary: This stopped working after 1 month. Within the first week out of the box, the display became decreasingly bright and within a month it would no longer display anything, seems completely dead. It has had plenty of opportunity to absorb sunlight, and for the first couple days it worked well, but it was all downhill after that. Disappointing for $20.
Summary: This calculator is larger than I expected. I love the color of it. I don't recall ever seeing a calculator this color. I like the seamless look of the keypad. The numbers are large and it has the functions necessary for me to work with. I have a feeling that it might end up leaving my desk as my previous calculator did so I will have to put my name on this one because I will be annoyed if it is not returned.
Summary: Needed a calculator at the office as it took too many steps to dig up the Calculator app on my phone. Could not settle with a cheapo 1 dollar calculator either as working at a design firm requires that I look like a designer too, and buy designerly things. Joking aside, the calculator is very nice looking and enjoyable to use.
