I love my little calculator! I use it all the time, for work and personal. The large buttons make it easy to use, along with the large numbers on the screen. It is lightweight, easy to carry. The color is vibrant, so you cannot misplace it, it stands out.

cute and popular
Love the thick, tall buttons that makes typing with accuracy much easier. It is super cute and my coworkers ask me about it because of its unique appearance. It seems like it's good quality. I do wish it was solar, but so far the batteries are lasting with occasional use.

Functional & Cute
Love this calculator. It’s 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. It’s the perfect color and size that I can easily find it on my desk. Plus it’s cute.

Cute calculator
Very cute and the buttons are hard. It is not solar powered it’s bather operated. It feels durable and easy to read and make calculations. It does thankfully turn off by itself too.

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!

34+35=Math Class...never was good
I really like this calculator. It is super cute! I love the color, the size, the way the buttons feel and sound (especially if you are into ASMR). Happy with this purchase. And it even does the thing i hate the most--MATH.

Short lived cutie
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.
