### ⭐⭐⭐⭐⭐ Review
*by N***A on 21 January 2026*

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.
