Functional & Cute
Love this calculator. Itās chunky enough that it sits well on the desk. Buttons are easy to read. I have a large calculator that runs a tape, and find myself using my phone or computer calculator often. This is the perfect middle man that will streamline simple calculations. Itās the perfect color and size that I can easily find it on my desk. Plus itās cute.

Cute and practical
Large enough to see all the numbers, super cute typewriter vibes because I love the clicking noise! Definitely good price for quality. Itās actually a little heavy than I thought, which is good because it means itās sturdy.

Fun colors, easy to use
Cute, chunky look but light weight. Super fun colors. Easy to use basic functions. Keys depress easily. Battery is easy to replace simply by sliding door on back (no tools required). Non skid tabs on bottom. Display is easy to read. Automatically shuts off after 10 min.

Cute, bulky
I was in a hurry. So my issues are my own fault and I did not deduct stars for them. I am very picky. I do a lot of numbers crunching due to my home business. I got tired of using my phone’s calculator or the computer calculator. So I turned to Amazon to find me a cute, clicky, large calculator that I could easily balance out all my stuff throughout the month. There were so many! I settled with this one because I have purchased items from this brand before and have always been happy. I liked the color shown in the photos. It matched my desk decor. And I liked someone’s video showing how clicky the buttons are, which I love. – My issues. Things I didn’t consider, which I should have. Closeness of the numbers, layout of the number buttons and other buttons. I should have paid attention to see if the layout was the same as a number pad, which is what I am used to. This is not. Some say what is the big deal? Well, I am so used to a regular number pad (computer) that I have become pretty fast with input. I saved a project for today when I got the calculator, and I found that the layout differences and the closeness of the buttons really hindered my ability to efficiently balance my monthly income. I had to one finger peck it rather thank use my 3 fingers like I am used to. If you don’t hit the buttons all the way, the number won’t register. I realized it is because the whole layout is off. Now, this is MY fault. Not the fault of the item. I should have thought about this before purchasing a calculator. I am not sure if I will keep it, my daughter may want it. But I will have to get something new and this time pay attention to the things I didn’t think about the first time. – The negative that is not exactly the fault of anyone either is the color accuracy. I know well enough that the color of the item may not really match the color shown on screen. I ordered pink. The screen shows a nice bright pink. The item itself is more of a muted pinkish color, leaning more towards a purple. I tried to take a photo but of course it just doesn’t show the difference accurately compared to the stock photo. – All in all, it is a cute calculator. It works and it I love the “00” button. I would recommend it for anyone who just needs a nice regular calculator!

Easy to use !
Very cute in person and aesthetically pleasing!!! As someone who has a slight obsession with the color pink, this calculator is the perfect color. The bubble letters have made it easy for me to calculate numbers. It is battery operated with one triple A and Iām interested to see how long a battery lasts. Overall, I think itās great for everyday office use and to add color to your desk.

Math. But cuter.
It’s a calculator that is great for calculating and has yet to give me poor mathematical advice! Love the color and style, and honestly no one can come to my desk without either complimenting it or trying it out themselves. It’s really just a calculator but a little more whimsical.

It works fine but buttons are a bit cheaply made
