SHOPSTAFF Rating Score

#15

Ranked #15 out of 56 products in Category

4.1

Overall Rating

The TI-30XIIS is a standard scientific calculator suitable for basic to intermediate math and science. It lacks advanced features found in higher-end models. It is durable and reliable for everyday use. It is positioned as an affordable option for students.

Display Type and Readability

4.0

Rating Criteria Explanation

The display is the primary interface for a scientific calculator. Consider the type of display (LCD, LED), the number of lines it shows, and the size of the characters. A multi-line display allows you to see both the input expression and the result simultaneously, which is extremely useful for complex calculations. Good contrast and adjustable brightness are also crucial for readability in various lighting conditions. A clear and easy-to-read display minimizes errors and improves the overall user experience, especially during long calculation sessions.

Rating Comments

The LCD display provides adequate readability for most users. The two-line display is helpful for viewing both the input and the result. The contrast is good, but not exceptional in all lighting conditions.

Functionality and Number of Built-in Functions

3.5

Rating Criteria Explanation

Scientific calculators come with a wide range of built-in functions, including trigonometric functions (sin, cos, tan), logarithmic functions (log, ln), exponential functions, statistical functions, and more. The number of functions and the ease of accessing them are important factors. Make sure the calculator includes the functions you need for your specific applications, whether it's for school, engineering, or scientific research. Look for calculators that offer quick access to commonly used functions through dedicated buttons or clear menu structures. Having enough functions prevents you from needing external resources during critical tasks.

Rating Comments

It includes essential functions for general math, algebra, and trigonometry. It may lack some of the more advanced functions needed for higher-level coursework or professional applications. The number of functions is not specified.

Calculation Accuracy and Precision

4.0

Rating Criteria Explanation

Accuracy is paramount for any scientific calculator. The calculator should perform calculations with minimal rounding errors and provide results with sufficient precision. Check the calculator's specifications for the number of digits it displays and its internal precision. While most calculators offer acceptable accuracy for everyday use, some models are designed for higher precision, which is essential for demanding scientific and engineering applications. Pay attention to reviews and tests that assess the calculator's accuracy in performing various calculations.

Rating Comments

The calculator provides sufficient accuracy for most common calculations. It is reliable for basic to intermediate mathematical tasks. It is not designed for high-precision scientific or engineering applications.

Ease of Use and Ergonomics

4.5

Rating Criteria Explanation

A scientific calculator should be easy to use, with a well-organized keyboard layout and intuitive menu navigation. Consider the size and spacing of the keys, the tactile feedback they provide, and the overall comfort of holding and using the calculator. A good ergonomic design reduces fatigue and improves accuracy, especially during extended use. Look for calculators with a logical arrangement of functions and clear labeling of keys. Some calculators also offer features like replay functions to review and edit previous calculations easily. A user-friendly design significantly enhances productivity.

Rating Comments

The calculator is designed for ease of use, with a clear layout and intuitive button placement. The keys are well-spaced and provide good tactile feedback. It is comfortable to hold and use for extended periods.

Power Source and Battery Life

4.0

Rating Criteria Explanation

Scientific calculators typically use batteries (AAA, AA, or button cells) or solar power, or a combination of both. Consider the type of power source and the expected battery life. A calculator with long battery life is essential for users who frequently use it for extended periods. Solar-powered calculators are a good option for environments with ample light, as they reduce the need for battery replacements. Some calculators also have an auto-power-off feature to conserve battery life when not in use. Hybrid models that combine solar and battery power offer the best of both worlds.

Rating Comments

The combination of solar power and battery backup ensures reliable operation. The battery life is sufficient for typical use. Solar power helps extend battery life in well-lit environments.

Durability and Build Quality

4.0

Rating Criteria Explanation

A scientific calculator should be durable enough to withstand everyday use and occasional drops or bumps. Look for calculators made from sturdy materials with a solid construction. A protective cover or case can also help to prevent damage to the display and keys. Consider the environment in which the calculator will be used. If it will be frequently carried in a backpack or used in a harsh environment, a more rugged model is recommended. A durable calculator will last longer and provide a better return on investment.

Rating Comments

The calculator is made from sturdy materials and is designed to withstand everyday use. It is durable enough to survive occasional drops and bumps. It is a reliable tool for students and professionals.

Manufacturer Reliability and Warranty
