A Comprehensive Review of the NEWYES NY-991ES Plus Scientific Calculator with Erasable LCD Writing Table
Introduction
Scientific calculators have come a long way, and the NEWYES NY-991ES Plus is a prime example of modern innovation. With an integrated erasable LCD writing tablet, this calculator stands out from the crowd. As an avid collector of Hewlett-Packard calculators with a penchant for RPN-based models, I was initially skeptical about branching out to explore this newcomer. However, the curiosity got the best of me, and I decided to give it a shot. In this comprehensive review, I’ll delve into the details of the NEWYES NY-991ES Plus and share my thoughts on its features, design, and functionality.
Unboxing Experience
The NEWYES NY-991ES Plus arrives in a high-quality, sturdy box that exudes an Apple-like sense of premium packaging. The white cardboard box is well-fitted, ensuring the device’s protection during shipping. Opening the box, I found the calculator itself and an impressively substantial 72-page manual, written in clear English. Unlike the typical single-page manuals of most affordable calculators, this detailed manual provides ample guidance.
Design and Build
The first thing you’ll notice about the NEWYES NY-991ES Plus is its solid build. Unlike some of its competitors, this calculator is surprisingly thick and substantial, measuring around 15cm when closed. It even features a magnetic closure that keeps the slate securely in place, preventing it from flopping around. The slate doesn’t flip around the back, so it lays flat on your desk. The calculator side includes a stylus in the lower right corner, securely inserted, and the top edge houses the battery compartment and a lock/unlock switch for the slate, a feature that distinguishes it from many competitors.
Erasable LCD Writing Tablet
The erasable LCD writing tablet is where the NEWYES NY-991ES Plus shines. The green “ink” on the screen could be a tad brighter, but it remains clear in well-lit environments like a classroom. Even in low light, it remains readable, though slightly more challenging. The “clear” button, located as a round button at the top of the calculator, instantly wipes the slate if it’s unlocked. If it’s locked, the button has no effect. This lock/unlock feature is a standout, as many similar devices lack it, making accidental erasures all too common. The electrical connection for screen erasing is via a small copper flex ribbon cable near the upper hinge. While it’s small and unobtrusive, its durability over time may be a slight concern.
Functionality
The calculator itself closely resembles the Casio 991ES Plus model in terms of button layout and functions. It mirrors the Casio’s functionality while looking very similar to the 991EX ClassWiz calculator. The button layout remains almost identical to the 991ES model, making it comfortable for those accustomed to Casio’s design. Notable missing features in the NY-991ES Plus compared to the 991EX model include the spreadsheet feature, graphic menus, the QR code feature (a Casio standout), and a few additional screens and functions. However, these omissions are unlikely to be noticed by the majority of users.
The keyboard’s quality is decent, with well-shaped keys that minimize missed or double presses. While it doesn’t match the tactile feel of an HP calculator, it performs admirably for its category.
Design and Finish
The NEWYES NY-991ES Plus boasts a textured matte black surface similar to the 991EX model. Key legend colors are acceptable, though not as vibrant as Casio’s. Despite some minor color differences, the calculator maintains a professional and sleek appearance. The added thickness, which differentiates it from other models, might be attributed to the stylus storage, but it imparts a sense of sturdiness and heft to the device.
Conclusion
In conclusion, the NEWYES NY-991ES Plus is a commendable scientific calculator with an innovative erasable LCD writing tablet. Its design, functionality, and build quality make it a worthwhile addition to the world of scientific calculators. While it may lack a few features found in the 991EX model, its strengths more than compensate for these omissions. With its lock/unlock feature, the calculator minimizes accidental erasures, a common issue with similar devices. This calculator is an excellent choice for students and professionals in need of a reliable scientific calculator with the added benefit of a versatile writing tablet. While the manual could use some improvement, it shouldn’t deter potential users from considering this impressive device. The NEWYES NY-991ES Plus is a valuable tool that combines traditional scientific calculator functionality with modern innovation.
