Cheap mouse exposes the MX Vertical’s biggest flaw

The quest for the perfect ergonomic mouse is a lifelong journey for anyone who spends significant time at a desk. For years, I settled into the embrace of the Logitech MX Vertical, finding relief in its design that allowed my arm to rest at a more natural angle, mitigating strain and fatigue.

It became such an integral part of my setup that I even travel with it—a testament to its comfortable fit. However, when ProtoArc approached me with their budget-friendly option, the EM11 Pro, I approached the comparison with healthy skepticism. Could a newer design truly offer something better than the established ergonomic standard?

While the MX Vertical excels in form and function—offering excellent wireless performance and robust construction—the challenge lies in finding that sweet spot where comfort meets true innovation. Placing the two mice side-by-side revealed some fascinating differences in how they interact with the human hand.

The Hand Fit Dilemma

The geometry of the two mice tells a compelling story about palm fit. The Logitech design lies flush against the palm, allowing the hand to naturally contour around the body of the mouse. However, this flush design often leaves a noticeable gap between the fingers and the buttons.

In contrast, the ProtoArc EM11 Pro features an elongated base with a curved front. While this curvature offers more space behind the buttons, it doesn’t necessarily feel flush with the palm. For some users, the flared bottom causes the hand to instinctively want to turn over more than desired, challenging the goal of a neutral resting angle.

Beyond Simple Movement

Ergonomics is not just about the shape; it’s about the entire input experience. This is where the ProtoArc mouse introduced features that significantly altered my workflow. The EM11 Pro boasts two separate scroll wheels: one for vertical navigation and another dedicated to horizontal scrolling.

This dual-wheel system transforms spreadsheet work, offering a much smoother, less fatiguing method of navigation compared to relying solely on the single scroll wheel and keyboard shortcuts. It removes the need for extra wrist movement, streamlining tasks like navigating complex documents in Excel or Google Sheets.

The Silence Factor

In the context of a home office, working with coworkers or family often means minimizing noise. The difference in acoustic feedback between the two devices was striking. While the Logitech MX Vertical can be somewhat clicky, the ProtoArc EM11 Pro operates almost completely silently. This quiet operation makes it an ideal choice for shared workspaces where noise control is paramount.

Ultimately, while the Logitech MX Vertical remains a highly respected piece of technology, the comparison highlights that true ergonomic excellence requires compromise. Both designs offer unique advantages; one prioritizes a classic contoured fit, and the other delivers specialized input features. The lesson moving forward is clear: future ergonomic mice must prioritize adaptability, offering diverse design options to accommodate the wide spectrum of hand sizes and resting styles.
