Pleased with the calculator and the price
I bought this for the school year. The calculator seems durable with good button response upon testing since school hasn’t started here yet. I don’t anticipate problems. The price was very good and I’m pleased with this order.

Very nice 👍
⭐️⭐️⭐️⭐️⭐️ 🧮 I really like the CATIGA CS-229 — it’s a solid little calculator that manages to feel both beginner-friendly and advanced. The graphing display is super helpful for visualizing equations, and with over 360 functions (fractions, stats, regression, complex numbers, etc.), I feel ready for everything from algebra to calculus. The screen is clear and detailed, the buttons are easy to press, and it handles a lot without getting awkward. 🔋 The design is compact enough to toss in a backpack, and it’s powered by battery and solar—so it works wherever I take it. The reset button in the back is a bonus if it ever acts up. 📚 Great tool for high school or college students, or anyone who wants a dependable calculator that can grow with them. Highly recommend — worth the pick!

Affordable but the Display Can Be Confusing
This calculator is very affordable, which is its biggest plus. It works fine for basic calculations and is a good option if you’re on a budget. However, the way it displays answers is confusing. When working with logs or powers of 10, it doesn’t clearly show the scientific notation. As shown in the attached photo, the power of 10 isn’t obvious, unlike on a basic Texas Instruments calculator that clearly shows ×10ⁿ. It’s usable and inexpensive, but you have to be extra careful reading the answers.

No backlight and slow reaction causes errors
I like the calculator but I wish it had a backlight. Also, when I type quickly, it’s too slow to keep up so I have to go slower or typed entries are skipped.
