The Logitech MX Master 3S stands as the undisputed champion of productivity mice, especially for professionals, creatives, and power users. Its ergonomic design feels like a natural extension of your hand. Furthermore, its precision 8K DPI sensor tracks flawlessly on virtually any surface, and the revolutionary MagSpeed scroll wheel switches seamlessly between precise scrolling and hyper-fast coasting. It is truly hard to find fault with this device.

The customizable buttons, managed through Logitech’s intuitive Options+ software, allow you to create application-specific profiles. As a result, these profiles genuinely accelerate your workflow. Whether you’re editing videos in Premiere Pro or designing in Photoshop, the MX Master 3S delivers a premium experience. However, there are compelling reasons to wait before buying one.

So, why the urgent warning? Why advise against purchasing what many consider the best mouse on the market today? The answer is simple. Because concrete evidence points to the MX Master 4 launching very soon, and the improvements are expected to be significant.

This conclusion isn’t based on speculation. Instead, official regulatory filings have surfaced that paint a clear picture. Agencies have already cleared the device, believed to be the upcoming MX Master 4, for major regulatory hurdles. For instance, Brazil’s Anatel granted official homologation on **May 9, 2025**. Similarly, the FCC in the United States has processed the required filings. Curious about the leaked details? Read our full analysis of the upcoming Logitech MX Master 4 here.

Adding fuel to the fire, a slip-up on one of Logitech’s official social media accounts briefly showcased images of a new mouse. It clearly bore the unmistakable DNA of the **Logitech MX Master 3S** series but with subtle, important refinements. Although the images were removed quickly, tech enthusiasts captured them first.

So, what does this mean for you? If you’re considering purchasing the MX Master 3S today, you might want to hold off for just a few more weeks. All signs point to an imminent announcement of the next generation. Consequently, this could make the current model’s price drop significantly or simply leave you with buyer’s remorse.

Undoubtedly, the MX Master 3S remains an exceptional tool that has served millions of users brilliantly. However, with its heir apparent already clearing regulatory hurdles, patience might be the wisest strategy right now.
