This calculator is honestly so cute and functional. I love the soft pink color—it looks great on my desk and adds a fun touch without being distracting. The buttons are big, well-spaced, and very easy to press, which makes using it comfortable and satisfying, especially for longer calculations. The display is large and clear, so numbers are easy to read, and everything responds quickly with no lag. Brightness of numbers looks good. It feels sturdy and well made, not flimsy at all, and the mechanical-style buttons have a nice click to them. I also appreciate that it doesn’t slide around thanks to the rubber feet on the bottom. Overall, this is a great everyday calculator that combines function with a cute aesthetic. Perfect for work, school, budgeting, or even just keeping on your desk. Definitely worth the price and I’d highly recommend it. Read more

Doesn’t come with a AAA battery, but I had some in the junk drawer. This is a cutesy little calculator, if I have to have a basic calculator for testing purposes I at least wanted it to be cute. ☺️ It works as expected. Buttons are clicky and work well. Read more

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! Read more

When the calculator first arrived it was great! Super cute and worked well, very easy to set up and use. Just add a battery and go! The buttons reminded me of a typewriter and even has a satisfying “click” for those that need a tactile feel when using a calculator. However, after about 8 weeks it turned off and did not turn on again. Changing the batteries did not help and the support page is centered around the printing calculator. Disappointed that I got such a short amount of use. Read more
