Reliable and sturdy
I dropped this twice already and it still works perfectly. The solar panel ensures I never run out of battery during long study sessions. Highly recommend for high schoolers.

Exam compliant
Checked the list of allowed calculators for the FE exam, and this model is explicitly listed. Works great for construction calculations and unit conversions.

Good screen visibility
The display is large and clear, which is helpful when working on complex equations. Took off one star because the protective cover feels a bit flimsy, but the calculator itself is solid.

Best budget scientific calculator
Compared to other brands costing twice as much, this Deli calculator offers the same functionality. It's been a lifesaver for my graduate entrance prep.

Great value for college engineering
Using this for my introductory engineering courses. It handles trigonometry and statistics well. The only downside is the manual could be more detailed, but online guides helped.

Perfect for the SATs
Bought this for my daughter's upcoming SAT exam. It has all the necessary functions without being overly complicated. The buttons are responsive and easy to press during a timed test.
