Just the right size for high school students to use.

Good, but not practical for long calculations.

Fragile, but serves its purpose

Scientific Calculator with 240 Functions and Two-Line Display

I loved it, it's perfect, it has all the functions of a scientific calculator, comes with its batteries and well sealed, it also comes with its manual 💗

Overall, the calculator does its job, but the quality of the materials and the paint looks very cheap, although the price is understandable. Overall, for this price it's acceptable.

The button feels a bit cheap, but it's still good.

Quality matches the description

A very good calculator worthy to use.

Lightweight material, meets the requirements

2 batteries built-in, simple calculation processing ok, keyboard click feel not good, not recommended if you click a lot, I bought it just to try it out, so far it works well.

Excellent calculator, this is the second time I've bought it in several years.

Great product, comes with battery inside
