Logitech MX Master 4 Review: Worth the Upgrade

You’re probably here because the Logitech MX Master 4 has been making noise as the latest productivity mouse, and you’re wondering whether it’s a genuine upgrade or just another refresh. With haptic feedback, refined ergonomics, and a USB‑C Bolt receiver, it’s tempting—but the real question is how it stacks up against its sibling, the MX Master 3S and the vertical MX Lift.

Time savings: up to 33% · Haptic feedback: Yes · Connectivity: Bluetooth, Logi Bolt · Battery life: Up to 70 days · Max DPI: 8000

Below are the key specifications for the Logitech MX Master 4:

Is there an MX Master 4?

Yes—the Logitech MX Master 4 is a real, shipping product. According to the RTINGS hardware lab, it is positioned as the direct successor to the MX Master 3S. It debuted in 2024 and is available on Logitech’s own website and through major retailers. The key additions over its predecessor are haptic feedback, a new side gesture button, and a USB‑C Bolt receiver (Cameron Dougherty Tech review).

Logitech’s official page confirms the model, and retailers have stock. The real question is whether the upgrades justify the price for your workflow.

Confirmation of product availability

• Listed on Logitech’s official product page as a current model.
• Sold at Amazon, Best Buy, and other electronics retailers.

The MX Master 4 replaces the 3S as the flagship in Logitech’s MX line, and early reviews confirm it is widely in stock.

Official Logitech product page

Logitech’s own marketing claims a “save up to 33% of your time” benefit, driven by the haptic feedback and MagSpeed scrolling. Independent testing has not yet verified that exact figure in controlled conditions, but the hardware is clearly shipping.

Is the Logitech MX Master 4 worth it?

At around $100, the MX Master 4 asks a premium over basic mice. The answer depends on how much you value haptic feedback and ergonomic refinement.

• Price vs value: One reviewer notes the price gap between the MX Master 3S and 4 is typically $20–$30, making the 4 a modest extra investment for the latest features.
• User sentiment: A HeyUpNow forum post claims both models offer up to 70 days battery life and 3‑device pairing, but real‑world reports from Reddit show mixed experiences with battery longevity.
• Productivity gains: The haptic feedback and larger palm rest reportedly reduce hand fatigue during long sessions (RTINGS).

The trade‑off: Users who already own a MX Master 3S may not feel a strong pull to upgrade unless they need the USB‑C receiver or the slightly larger palm area. First‑time buyers, though, get the best‑in‑class productivity mouse without compromise.

The choice depends on your need for haptic feedback and USB-C connectivity.

What’s the difference between Logitech MX Master 3 and 4?

The MX Master 4 adds haptic feedback, a side gesture button, and a USB‑C Bolt receiver—none of which the original MX Master 3 offered.

Three differences, one pattern: the 4 is a refinement of the 3’s formula.

The pattern: Logitech kept the shape nearly identical but upgraded sensor resolution and added a tactile feedback layer. For most users, these changes matter only if they frequently use gestures or work with high‑resolution monitors.

Is MX Master 4 better than 3S?

The 4 vs 3S choice is the most common comparison. Both mice share the same 8000 DPI Darkfield sensor and 70‑day battery claim. The key differences come down to feel and connectivity.

• Haptic feedback vs silent clicks: The 4 has haptic scrolling; the 3S uses silent, low‑force clicks. RTINGS notes the 4’s buttons are larger and the palm rest is expanded.
• Scrolling: The 4 offers MagSpeed scrolling (free‑spin or ratchet); the 3S has SmartShift. Both are smooth, but the 4’s haptic feedback adds a discrete click feel.
• Price: The 4 runs about $20–$30 more (YouTube reviewer).

The catch: If you work in a quiet office, the 3S’s silent clicks are a genuine advantage. The 4’s haptics aren’t loud, but the scroll wheel has a faint tactile hum. For home offices, the 4’s extra features tip the scale.

In short, the 4 offers new tactile features but the 3S remains a strong silent contender.

Is MX Master 4 better than MX Lift?

The MX Lift is a vertical ergonomic mouse, completely different in shape and intent. The MX Master 4 is a traditional curved mouse with more buttons and features.

• Ergonomics: The Lift puts your hand in a handshake position to reduce wrist strain; the Master 4 keeps your hand flat. RTINGS describes the 4’s shape as refined but still traditional.
• Productivity features: The MX Master 4 has far more programmable buttons, gesture support, and the Action Ring. The Lift is simpler, targeting comfort over customisation.
• Target user: If you already have wrist pain or use a mouse for 8+ hours daily, the Lift is the safer choice. If you want maximum workflow speed and don’t suffer from RSI, the Master 4 wins on features.

The trade‑off: You can’t have both a vertical grip and a high‑button‑count productivity tool in one package. Choosing between them is a decision about your physical needs first, feature needs second.

— Cameron Dougherty Tech review

User opinions vary, but the general consensus points to a solid upgrade for specific users.

Summary

The Logitech MX Master 4 refines an already excellent productivity mouse with haptic feedback, a USB‑C Bolt receiver, and subtle ergonomic tweaks. For productivity users who work in front of a screen all day and value every micro‑interaction, the $20–$30 premium over the 3S buys genuine time savings. For budget‑conscious buyers or those with wrist sensitivity, the MX Lift or a discounted 3S remains the smarter play. If you experience wrist strain, the MX Lift’s comfort takes priority; otherwise, the MX Master 4’s features lead.
