Good value for the price

Does everything it promises. The voice feature is a nice touch for younger kids. Only wish the case was included, but overall a solid purchase for elementary math.

Teacher approved!

Our teacher recommended a calculator that aligns with the Su Jiao and Ren Jiao editions. This one fits perfectly. The mini size fits easily in pencil cases.

Perfect for my daughter's math class

This calculator matches exactly what is needed for the Grade 4 Ren Jiao textbook. The voice feature helps her check her work without me needing to hover over her shoulder. The pink design is adorable too!

Great functionality, cute look

Bought this for office use because I liked the compact size, but it's clearly designed for students. The voice prompts are clear and not annoying. Buttons are very responsive.

Helps with homework confidence

My son was struggling with volume 2 math concepts. The specific functions aligned with his curriculum made a huge difference. He feels more independent doing his exercises now.

Sturdy and reliable

It has survived being dropped twice already. The battery life is excellent thanks to the solar panel. The aesthetic is very modern compared to old gray calculators.
