Claro CL-500C Check & Correct Calculator Review: A Solid Performer for Error-Prone Tasks

Desktop Calculator Claro CL-500C  

The Claro CL-500C positions itself as more than just a basic desktop calculator. With its prominent "Check & Correct" branding, it targets users—from office accountants to students—who need reliability and the ability to easily fix mistakes without starting a calculation over.

First Impressions and Build Quality
The CL-500C has a classic, no-frills desktop calculator design. It's built from lightweight but durable plastic, making it easy to move around a desk or pack in a bag. The keys are large, plastic, and well-spaced, providing a satisfactory tactile feedback that is crucial for rapid data entry. The two-tone color scheme is professional and clean. While it may not win design awards, its functionality-first approach is clear.

Standout Feature: The Check & Correct System
This is the calculator's main selling point, and it delivers. The CHECK, CORRECT, and DELETE keys allow you to scroll back through your last 99 calculation steps. If you spot an error—a wrong number or an incorrect operation—you can navigate to that step, correct it, and the calculator will automatically recalculate the entire sequence with the new value. This is an invaluable feature for long, complex calculations and eliminates the frustration of having to clear everything and start from scratch after a single mistake.

Display and Basic Functions
The "Big Display" or "Large Display" is easy to read, with digits that are bold and clear from a distance. The basic arithmetic functions (+, -, x, ÷) work flawlessly. It includes essential tools like a Grand Total (GT) key to keep a running sum of calculations, a Mark-Up (MU) key useful for quick profit margin calculations, and a three-key independent memory system (M+, M-, MR/MB) for handling sub-totals.

Additional Useful Features

• 00 Key: A dedicated double-zero key speeds up entry of larger numbers.

• Change Sign (+/-): Quickly makes a positive number negative or vice versa.

• Percent Key (%): Handles percentages with ease.

• Paper Roll Simulation: The ability to check your work mimics the functionality of a printing calculator, offering a clear audit trail without the need for paper.

Who Is This Calculator For?
The Claro CL-500C is an excellent choice for:

• Office Professionals: Handling invoices, expense reports, and financial data where accuracy is paramount.

• Students: Especially those in accounting or finance courses, who can use the check feature to learn from and correct their errors.

• Home Office Users: Anyone who regularly works with numbers and values a hassle-free way to fix entry mistakes.

Potential Limitations

• The calculator is not scientific, so it's not suitable for advanced mathematics, engineering, or trigonometry.

• The display, while large, is not a modern high-contrast LCD, which might be a minor issue in very low light.

Verdict

4.5 out of 5 Stars

Its robust feature set goes far beyond the basics, with the innovative Check & Correct system being a genuine game-changer for productivity.
