ProtoArc EM25 Review: Our Verdict on this Budget Ergonomic Mouse

Our verdict on the ProtoArc EM25 is that while it offers a budget-friendly entry point for users seeking an ergonomic shape, the lack of refinement and poor control implementation makes it difficult to recommend. At In Game News, we have spent significant time testing this peripheral to see if it stands up to the high standards set by industry leaders like the Logitech MX Master series.

If you are a PC user who spends long hours at a desk, you have likely encountered the ergonomic mouse market dominated by premium options. The ProtoArc EM25 arrives as a direct challenger, attempting to deliver the features of a high-end productivity tool at a fraction of the cost. However, our testing indicates that the gap between budget hardware and premium peripherals remains significant.

Design and Ergonomics

The ProtoArc EM25 is clearly designed to mirror the aesthetic and functional profile of the Logitech MX Master 3S and MX Master 4. It features a similar chassis shape and an extended thumb rest that aims to support the hand during extended work sessions. For those who prioritize comfort over premium build materials, the general shape is acceptable. It rests naturally in the hand, and the ergonomic intent is clear from the initial setup.

However, the material choices leave much to be desired. The mouse features a tacky, satin-finish coating that feels less durable than the premium textures found on more expensive alternatives. The buttons themselves feel "plastic-fantastic," lacking the tactile satisfaction one might expect from a daily driver. While the chassis has a certain level of solidity, the overall construction feels unrefined, constantly reminding the user that they are utilizing a budget-tier device.

Performance and Control Implementation

The most significant disappointment with the EM25 lies in its performance. While the main switches are quiet and offer a decent click, the implementation of the other controls is inconsistent. The mouse includes two scroll wheels—one of which features a clutch—but both feel clumsy and imprecise during operation. Every time we attempted to use the secondary controls, the experience felt slightly wrong, leading to a lack of confidence in the device's reliability.

Beyond the button feel, the physical movement of the mouse across a desk surface is hampered by poor design choices. The skates on the underside of the EM25 feel rough and edgy, as if they were never properly finished or sanded down during the manufacturing process. This results in a scratchy, uneven glide that detracts from the ergonomic promise of the chassis. For a device intended for productivity, this lack of smoothness is a major drawback.

Value and Market Positioning

Priced at $50 / £29, the ProtoArc EM25 is objectively inexpensive compared to the flagship mice it attempts to emulate. For users who are on a strict budget and simply must have an ergonomic shape with quiet switches, the EM25 might appear to be a viable choice. However, we suggest that users consider the long-term value of investing in more refined hardware. Our team at In Game News believes that for most users, saving up for a more reliable, better-constructed mouse will provide a significantly better experience over time.

Why the EM25 Struggles to Compete

To provide a clearer picture of where the EM25 stands, we have summarized the key areas where it succeeds and where it falls short:

• Comfortable Shape: The ergonomic design is effective for its intended purpose.
• Quiet Switches: The main buttons are surprisingly pleasant and quiet for office environments.
• Clumsy Controls: The secondary buttons and scroll wheels lack precision.
• Poor Glide: The skates are rough and create friction during use.
• Build Quality: The materials feel cheap and lack the refinement of competitors.
