In this guide
The MX Master 3S on Logitech's UK store today is the Bluetooth Edition, part 910-007501, listed in graphite only at £89.99 and in stock on October 16, 2026. The name matters. The carton holds the mouse and a leaflet; the Logi Bolt receiver that came with the original release is gone, and so is the charging cable. The part number differs from the 910-007499 sold in some other regions, but the product name, the box contents and the specification table are those of the same Bluetooth Edition.
What stays is the hardware people buy this mouse for: a Darkfield sensor that runs from 200 to 8,000 DPI, a MagSpeed electromagnetic scroll wheel, a thumb wheel, a gesture button, and switches that Logitech says put out 90 percent less sound power than the MX Master 3. The sections below take the published numbers, compare them with the £54.99 M720 Triathlon that also switches between three computers, and work out which desks lose something by the missing receiver.
Our verdict
A strong pick for a desk with Bluetooth on every computer and a spare USB-C cable in a drawer; on a Bluetooth-less desktop, the missing receiver turns £89.99 into £101.98 once a Logi Bolt receiver is added.
- A good fit for
- Laptop users who move between two or three machines, want a thumb wheel and an electromagnetic scroll wheel, and care about click noise in a shared room.
- We would skip it if
- Your computer has no Bluetooth radio and no free USB port for a receiver, you want a cable in the box, or a £54.99 M720 already covers three-device switching for you.
Reasons to consider it
- Darkfield sensor adjustable from 200 to 8,000 DPI that tracks on glass 4 mm or thicker
- MagSpeed electromagnetic wheel that shifts between ratchet and free spin on its own as you scroll faster
- Logitech claims 90 percent less click sound power than the MX Master 3, up to 70 days per charge and a 2-year warranty
The compromises
- Package contents are the mouse and documentation: no Logi Bolt receiver and no charging cable
- Not compatible with Unifying receivers, and Logi Options+ runs only on Windows and macOS
- 141 g and 124.9 mm long, a large right-handed shape with no left-handed version
What we have not verified: No tracking, battery, noise or comfort was measured. Logitech gives the quiet-click claim as a percentage, not in decibels, and the three-computer figure comes from the support guide, not the store listing. Graphite was the only colour on the page and in stock at the £89.99 list price on October 16, 2026; the 2-year term comes from a support page that does not single out the Bluetooth Edition.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
MX Master 3S Bluetooth Edition Wireless Mouse
The 8,000 DPI Darkfield sensor, the electromagnetic wheel and the quiet switches are the full MX Master 3S feature set, at £89.99 with free returns for 30 days and a 2-year warranty.
Before you buy: No receiver and no cable in the box, Unifying receivers do not work with it, and full customisation needs Logi Options+ on Windows or macOS.

Logitech's package-contents line reads "Mouse" and "User documentation." The support guide for this edition spells out the rest: charge it with a Type-C to Type-C or Type-A to Type-C cable, not included, and if a Logi Bolt receiver is already in the drawer the mouse will pair with it. If you do not, Bluetooth Low Energy is the only way in, and the compatibility list adds that Unifying receivers will not work at all.
For a laptop desk the omission is a small footnote, since most laptops made in the last few years have Bluetooth and a Type-C cable is already on the desk for a phone. For a desktop tower without a Bluetooth radio it is the whole purchase decision: Logitech UK sells a Logi Bolt receiver at £11.99, in USB-A and USB-C versions, which puts the real price of that setup at £101.98. Check the computer first, then decide whether that total still suits you.
8,000 DPI on glass and a wheel that shifts modes on its own
The Darkfield sensor ships at 1,000 DPI and can be set anywhere from 200 to 8,000 in 50 DPI steps, though changing it needs Logi Options+, which Logitech offers only on Windows and macOS. Logitech says it tracks on glass with a 4 mm minimum thickness. On a monitor at 4K or higher the extra range matters; on a single 1080p screen the default setting is the one most people will keep.
The MagSpeed wheel is electromagnetic, and Logitech's copy calls it remarkably quiet. The support guide describes the mechanism plainly: a ratchet mode for lists that shifts to free spin as you scroll faster, with a mode-shift button on top to force either state and a sensitivity setting in the software. A second wheel under the thumb handles horizontal scrolling, and the app can remap it to zoom, brush size or tab switching per application.
Ninety percent quieter, as measured by Logitech, and seventy days between charges
Logitech's quiet-click claim is specific but not in decibels: compared with the MX Master 3, the 3S has 90 percent less sound power on the left and right buttons, measured at one metre. No absolute figure appears anywhere in the listing, so a buyer who needs a number for an open-plan office will not get one here. The claim covers the two main buttons; the thumb buttons and the gesture button are not part of it.
Logitech rates the battery at up to 70 days on a full charge, with three hours of use from a one-minute top-up and, per the support guide, a full day from three minutes. Both figures carry the usual usage caveat. Charging goes through the Type-C port, so the cable you supply also keeps the mouse running while it charges, and three LEDs on the side show the level: green above 10 percent, red below, pulsing green while plugged in.
Three computers, Flow, and what the £54.99 M720 already does
The Easy-Switch button on the underside cycles between three paired computers, a short press to change channel and a three-second hold to pair a new one. With Logi Options+ installed on both machines, Flow moves the cursor across the screen edge from one computer to the next and lets you copy and paste between them.
The M720 Triathlon, at £54.99, also pairs with three computers and includes a Unifying receiver and an AA battery, which is the fair comparison for a buyer who mainly wants device switching. Its wheel has a hyper-fast mode and tilts, but its UK spec table lists no electromagnetic wheel, thumb wheel, glass tracking or quiet-click claim, gives 1,000 DPI rather than the 3S's 8,000 range, and runs on an AA battery instead of a rechargeable cell. That Unifying receiver will not pair with the 3S. If none of those gaps changes your day, the cheaper mouse with the receiver in the box is the better buy; if two or more do, the £35 difference is the price of them.
A large right-handed shape, software on two platforms, and a two-year term
The mouse measures 124.9 mm long, 84.3 mm wide and 51 mm tall and weighs 141 g, and the sculpted thumb rest makes it right-handed only. Anyone with small hands or a fingertip grip should handle one before ordering; no fit or comfort was assessed here.
Compatibility runs to Windows 10 and 11, macOS 10.15 and later, Linux, ChromeOS, iPadOS 14 and Android 8.0, but Logi Options+ exists only for Windows and macOS, so on the other systems the mouse works with basic functions and no button remapping, DPI change or Flow. Logitech's UK support page gives a 2-year limited hardware warranty for the MX Master 3S; the store listing adds free returns within 30 days and free standard delivery on orders over £29.
Skip it for a receiver-only desktop; buy it for a Bluetooth laptop
Skip the Bluetooth Edition if the computer has no Bluetooth radio and you do not own a Logi Bolt receiver, because the missing part is exactly the one you would need, and Logitech UK charges £11.99 for it. Also walk away if customisation matters and your daily machine runs Linux or ChromeOS, since Logi Options+ does not exist there, and if a left-handed or compact mouse is what your hand wants. A buyer who only needs three-device switching gets that from the M720 for £54.99 with a receiver included.
Buy it for a laptop desk, or a pair of them, where Bluetooth is a given, a Type-C cable is already lying around, and the electromagnetic wheel, the thumb wheel and the quieter switches are the reasons for spending £89.99. That recommendation rests on Logitech's published numbers and the support guide alone. Tracking accuracy, click loudness, battery life and hand comfort remain unmeasured.
