Logitech just dropped the latest entry in its workhorse MX line — the MX Master 4 — and, as these things go, the news cycle moved faster than the product launches. The mouse officially lists at $119.99, but Best Buy is already selling multiple colorways for $89.99, a quick $30 knock-off that makes the new model feel like an impulse buy for a certain kind of desk worker.

Logitech MX Master 4

The MX Master 4 debuts with tactile haptics, a refreshed design, and a surprising $30 discount at Best Buy just a week after launch.

If you’ve used an MX Master before, the silhouette will look cozy and immediately recognizable: sculpted, chunky, built to cradle your hand through long editing or spreadsheet sessions. What’s new is less about the shape and more about the sense of touch — Logitech put a haptics module into the thumb rest, and built a software-centered “Actions Ring” that you trigger from the thumb area to call up shortcuts and tools. Those haptics are customizable: they can buzz to confirm actions, warn you about low battery, or — a neat little productivity cheer — give you a tactile nudge when the pointer crosses from one monitor to the next. Logitech says those features are designed to reduce friction and keep you “in the flow.”

What the haptics actually do

This isn’t a revolution in pointing devices — the haptics don’t add new gestures you couldn’t already map in software — but they do add a layer of tactile feedback that makes some existing features feel a touch smarter. Reviews and early hands-on writeups describe haptics as subtle and helpful rather than gimmicky: useful for confirming the Actions Ring or for that monitor-edge buzz, but not a reason on its own to sell your current mouse. If you already love the MX Master 3S, expect incremental refinement rather than a must-have leap.

Connectivity, internals and the little things

Logitech includes a USB-C Logi Bolt receiver in the box (no separate adapter required), claims improved radio performance compared with the 3S, and fits an 8,000-DPI sensor that’ll track even on glass. Battery life is quoted at up to about 70 days on a full charge, and the mouse supports a quick charge (minutes of charging for hours of use). Logitech also leans into durability and sustainability here: the shell’s plastic has a different finish that reviewers say feels tougher than the soft-touch coating on the 3S, and the product page highlights recycled materials in several components.

Logitech’s MSRP for the MX Master 4 is $119.99, which tracks with its product page and press coverage. Right now, Best Buy lists several variants (including Mac-flavored and Adobe editions) at $89.99, showing in-stock availability and the option to pick up in certain stores. That $30 off is the kind of launch discount that makes sense if you want the newest features without waiting for the usual post-launch markdowns. Treat it as a nice early adopter discount rather than permanent price positioning — Logitech’s site still lists the full price.

Who this upgrade actually helps

Buy it if: you spend long sessions with many windows or multiple displays and you want small, usable refinements (a quieter click feel, an Actions Ring that keeps common tools at your cursor, and haptic nudges that prevent pointer hunting). It’s also a sensible pick if you’re buying a new mouse for a Mac setup — Logitech shipped Mac-specific colorways and compatibility is broad.

Skip it if: you already own an MX Master 3S and you’re fine with its feel — the 4 is evolutionary, not revolutionary. If you’re price-sensitive, the 3S remains a capable machine and will likely drop in price as retailers cycle inventory. Reviews broadly call the MX Master 4 an excellent mouse that pushes the series forward, but not one that compels an instant upgrade for every 3S owner.

Final bit of practical advice

If you’re tempted by the Best Buy price, check the product pages for the exact SKU you want (different editions and colors are showing slightly different stock and pickup times) and factor in returns or recycling trade-in offers if you want to offset cost. If you’re on the fence, wait a week or two: post-launch deals often tighten up, but the $89.99 price right now is legitimately attractive if you want the newest MX in your hand this month.
