Quick buying advice
- At the checked UK direct prices, MX Master 4 costs £119.99 and MX Master 3S Bluetooth Edition costs £74.99: a £45 difference.
- Choose the 4 if you will use its documented haptic functions in supported software. Shortlist the 3S Bluetooth Edition if scrolling, tracking and quiet clicks solve your task.
- Confirm the exact edition and receiver contents. A familiar model name does not prove that a USB receiver is included.

| Haptic hardware | Customisable feedback for supported actions. | Do not buy this edition expecting the 4’s haptic hardware. |

These prices are a dated direct-store comparison, not a UK-wide lowest-price claim. Stock was shown for the selected Graphite products. Discounts, bundles and retailer references can change. This comparison is specifically against 3S Bluetooth Edition; older receiver bundles and Mac editions need their own price and contents check.
How to interpret the “33%” productivity claim
Logitech attributes its “up to 33%” Actions Ring claim to an Ergo Lab study in 2025 with 37 MX Master users across eight desktop actions. This is a bounded manufacturer study, not evidence that your entire working day will become 33% shorter. Study description. Choose one repeated task—changing tools or navigating a spreadsheet—and check whether the application, permissions and shortcut configuration support the intended action.
| Your situation | Decision | Reason |
|---|---|---|
| A working 3S and no haptic need | Keep it unless a specific task remains awkward. | The £45 price difference is only part of the replacement cost. |
| New purchase with a tighter budget | Compare the 3S Bluetooth Edition first. | Both list 8K tracking; choose on useful controls and fit. |
| Creative app with supported haptic actions | Trial the 4 with that application. | Hardware value depends on a supported workflow. |
| IT-managed computer | Ask IT about Options+ and connection policy first. | Blocked software can remove the feature you paid for. |
Check the edition before price matching
Write the exact SKU, colour, receiver contents and seller beside each quote. Then compare delivered price and return terms. If you switch between a managed laptop and a personal computer, test the connection and saved settings on both. Comfort is also individual: keep keyboard position and desk height consistent when trying the mouse, and check reach to the thumb controls. Neither a higher DPI ceiling nor a study percentage establishes a comfortable fit for your hand.
Frequently asked questions
Is the 4 automatically more precise than the 3S?
Both named UK pages list 8,000 DPI tracking. Haptics and workflow controls are separate from that sensor ceiling; a larger price does not itself establish more precise work.
Is a 33% time saving guaranteed?
No. Logitech’s claim is tied to its stated study and selected actions. Your software, shortcuts and task mix determine whether you benefit.
Does Bluetooth Edition include Logi Bolt?
Check the selected SKU’s in-box list. Do not transfer receiver assumptions from an older 3S bundle to the Bluetooth Edition.
Should I buy the 4 for Linux?
Verify current manufacturer OS and software support for the required functions first. Basic connection and advanced Options+ features should not be treated as the same compatibility promise.
