Perfect for the Constructor Exam
I bought this specifically because it has no storage function, which is a strict requirement for the First-Class Constructor exam. It works flawlessly for all statistical calculations and complex equations. Highly recommended for anyone taking professional certification tests.

Reliable for Accounting Exams
As an accounting student, I needed a calculator that could handle financial functions without being programmable. This Deli model fits the bill perfectly. It's durable, lightweight, and the solar backup ensures the battery lasts a long time.

Great value for students
My daughter uses this for her high school math and statistics classes. The buttons are responsive and the display is clear. The only reason I didn't give 5 stars is that the manual could be more detailed in English, but the functions are intuitive enough to figure out.

Exam safe and functional
Verified by my proctor before my graduate entrance exam. The lack of memory storage is clearly marked and easy to verify. Performance is smooth, and it handles trigonometry and logarithms without any lag.

Best choice for standardized tests
Bought three of these for my tutoring center. Students find them easy to use, and we never have issues with them being disallowed in test centers due to prohibited features. Excellent product for the price.

Solid build quality
Good weight to it, doesn't feel cheap like some other brands. The key travel is satisfying. I use it daily for engineering calculations. Would be perfect if it came with a harder protective case, but the slide-on cover is decent.
Q: Does it come with batteries included?
A: Yes, the package includes one LR44 button battery pre-installed, plus a solar panel for extended usage life.
Q: Is the user manual available in English?
A: Yes, the box contains a multi-language manual that includes a complete English section detailing all 240+ functions and operation examples.
Q: Is this calculator allowed in the National First-Class Constructor Examination?
A: Yes, this model is specifically designed for that exam. It features no text storage or programming capabilities, making it fully compliant with current examination regulations.
Q: What is the difference between this and the standard DL-82ES?
A: This specific batch is certified and labeled for exam use where non-programmable devices are mandatory. While the core calculation engine is similar, this unit guarantees the absence of hidden storage partitions often found in generic scientific calculators.
Q: Can I store formulas in this calculator?
A: No, this calculator does not have any formula storage or programmable memory functions. This is a safety feature to ensure it meets strict exam security standards.
