CATIGA Desktop Calculator 8 Digit with Solar Power and Easy to Read LCD Display, Big Buttons, for Home, Office, School, Class and Business, 4 Function Small Basic Calculators for Desk, CD-8185 Black

I needed a new calculator as my eyes aren't what they used to be, and it was becoming difficult to see the display on my old one. This CATIGA Mechanical Switch Calculator is perfect! The numbers on the display are big and bright. I love that the colors are different shades of peach (my favorite, but it comes in many other colors, too). One caution: Initially, I did not remove the black plastic arrow on the back in the battery compartment. I wondered why the calculator worked only under my desk lamp. Well, the arrow keeps the battery from making full contact, so until I figured that out, I was operating only on solar. Once I removed the arrow, the calculator worked wonderfully. I love that the keys are raised and make a clicking sound, just like the old typewriters did when I was younger. (A while ago, I purchased a mechanical keyboard from Amazon that sounds like the old-time typewriters, too.) The fact that the keys are raised, as you can see in the photo, makes them easier to operate. All in all, I highly recommend this calculator! The price can't be beat, and neither can the functionality.

Love, love this calculator. Being elderly, I now find my old, dark calculator buttons and the piece itself didn’t stand out. Since I found this colorful one, I am so pleased. I can read it so much easier, not only with the color of the buttons and the piece itself, but also the large buttons. It’s not too small and not too large. I’m ordering another for my upstairs desk.

Great little calculator! The big buttons and clear display make it so easy to use, and I love that it’s dual solar and battery powered. Perfect for test situations where you're allowed to bring a basic calculator.

It’s a great little calculator. Easy to find and easy to use. Good for seniors.

Good value, large numbers and it's pink!

This calculator is sturdy, easy to use, and provides accurate calculations. Buttons are big, responsive and the display is clear. Exceeded my expectations and has been very handy for daily use.

Very pretty (purple). Works well. Is a little heavier than I expected. Very easy to read.

I bought the CATIGA Mechanical Switch Calculator (SD-1299) to use for my budgeting and expense tracking at work, and it’s been a solid addition to my desk. After several weeks of daily use, here’s what stands out: 👍 Pros: Comfortable, clicky keys: The mechanical switches feel great — very responsive with a satisfying “click.” It makes long budgeting sessions much easier on the hands. Large, easy-to-read display: The angled 12-digit screen is clear and visible even under different lighting conditions, perfect for double-checking numbers. Dual power source: Solar + battery means I never have to worry about it dying in the middle of a calculation. Sturdy and stylish: The retro, typewriter-style design actually makes it look nice on my desk, and the non-slip base keeps it steady when typing quickly. Accurate and fast: It handles continuous calculations smoothly — no lag or missed keystrokes. 👎 Cons: It’s a bit larger than typical desktop calculators, so if you have limited desk space, it might feel bulky. The retro aesthetic might not fit every office vibe — personally I like it, but it’s definitely more “cute” than minimalist. It’s best for standard calculations — not for scientific or advanced functions. ✅ Overall: If you’re looking for a reliable, comfortable, and good-looking calculator for budgeting, expense tracking, or everyday office math, this one is a great choice. The mechanical keys and solid build make it a pleasure to use, and it feels like it’ll last a long time.
