The MX Master 3S just hit $89.99 — PCMag’s top wireless mouse is 25% off
Verdict: Buy. The Logitech MX Master 3S is at $89.99 on Amazon right now — $30 off the $119.99 list, 39% below the 4-year average, and roughly where I’d expect it to land on Prime Day 2026 (June 23-26). If you don’t already have an MX Master, this is the moment.
This is a real, structural price drop, not a 3-hour coupon. The MX Master 4 launched in 2025 at $119.99 and Logi is actively clearing the 3S at this floor. The deal has been live for days and is unlikely to evaporate before Prime Day.
The deal
25% Off – Ahead of Prime Day
Logitech MX Master 3S Wireless Mouse (Graphite)
Logitech’s previous-generation flagship productivity mouse, now at $89.99 on Amazon — $30 off the $119.99 list. 8K DPI any-surface tracking, MagSpeed scrolling, quiet clicks, 70-day battery, and FLOW that moves your cursor between two computers. PCMag calls it their editor’s all-time top-rated wireless mouse.

But wait, the MX Master 4 is out — shouldn’t I buy that?
Short answer: no, not at this price gap. Amazon’s product page for the 3S now links to the newer MX Master 4 at $118.99 list (currently $119.99). The 4’s upgrades are real but marginal:
- Haptic feedback in the side button (4 only) — nice for app shortcuts, not a daily-driver feature for most people
- Slightly lighter and a tweaked thumbwheel position
- Actions Ring — an on-screen radial menu that mimics what Logi Options+ already does with a click
For $30 more than the 3S, you get a newer shell and some haptic flair. You do not get a better sensor, longer battery, or quieter clicks — the 3S already nailed those. Unless you specifically want haptics, the 3S at $89.99 is the smarter buy, and the 3S is fully supported by Logi Options+ going forward.
Why this mouse is worth the click
- 8K DPI, track on glass. No mousepad needed. Works on the back of a hardcover book if that’s what’s on your desk.
- 70-day battery, USB-C charging. One minute plugged in gets you three hours of use. Forget about it for two months at a time.
- MagSpeed scroll wheel. Free-spin mode scrolls 1,000 lines per second for long docs, then ratchets back for precision work.
- FLOW across computers. Move your cursor from your Mac to your PC, copy a paragraph on one, paste on the other. Works on Windows, macOS, and Linux.
- Three-device pairing. Switch between laptop, desktop, and tablet with a button on the bottom. Bluetooth + the included Logi Bolt USB receiver.
- Quiet clicks. 90% less click noise vs. the MX Master 3. Same satisfying feel, no angry coworkers.
Who this deal is for
Buy it if: You live in spreadsheets, browsers, or a dozen open tabs. You want a mouse that disappears into your workflow and never makes you think about charging it. You already use a mechanical keyboard and a real monitor and you’re building a desk that doesn’t suck.
Skip it if: You need a left-handed mouse (the 3S is right-handed only — the MX Master 3S Bluetooth Edition or another brand is your move). You game competitively (no high-DPI sniper button, polling rate tops out at 125 Hz). You already own an MX Master 3 or 3S and the new features don’t move the needle for you.

Price check
As of June 14, 2026, the Logitech MX Master 3S in Graphite is $89.99 new from Amazon, 25% off the $119.99 list, in stock with Prime shipping. The 6K+ bought-in-past-month badge and BSR #22 in Computer Mice suggest stock is moving but available. The deal has been stable at this level for several days.
Prime Day 2026 caveat: Prime Day runs June 23-26. There is a small chance the price dips another $5-10 during the event. If you see it under $80 on Prime Day, wait. Otherwise, $89.99 is the right price to grab it now — especially since the ATL of $76.99 was set in January 2024 on a 3rd-party seller, not Amazon-direct.
Alternative variants if you want to wait or save more:
- Performance (Black) variant — $84.95, different ASIN, 4.7 stars on fewer reviews. Cheaper, but the color is the main difference.
- Mac Edition — $84.99 list $99.99, different ASIN, ships without the Logi Bolt USB receiver (Bluetooth only). Skip unless you’re all-Mac and don’t need the receiver.
Frequently bought together: Logitech MX Mechanical Wireless Keyboard at $159.99 + MX Master 3S at $89.99 + Logitech Mouse Pad at $9.99 = $259.97 for the full productivity kit. If you’re rebuilding a desk, that’s the bundle to watch.
