Wireless productivity mouse for Kenyan developers, accountants and designers
Condition: New
Note: price and availability are subject to change without prior notice
Logitech MX Master 3S is now available at Mascom International for KSh 17,000, in stock at our Nairobi CBD store. The Logitech MX Master 3S carries an 8,000 DPI Darkfield sensor adjustable in 50 DPI steps, seven programmable buttons, a machined steel MagSpeed scroll wheel, a separate thumb wheel, and a 500 mAh rechargeable battery rated for 70 days per charge. Weight is 141 grams across a 124.9 mm by 84.3 mm by 51 mm body. Find the Logitech MX Master 3S at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD.
The Logitech MX Master 3S is built for people who spend six to ten hours a day inside spreadsheets, code editors, timelines and CAD drawings. Software developers in Westlands and Kilimani, CPAs pushing KRA returns before deadline, architects marking up plans, and video editors scrubbing footage all hit the same wall with a KSh 1,500 office mouse: cramped wrist posture, a scroll wheel that needs forty flicks to cross a long document, and clicking loud enough to annoy the desk next to yours. The Logitech MX Master 3S answers each of those directly.
Unlike other electronics retailers in Kenya, Mascom International lets you put your hand on the Logitech MX Master 3S before you spend a shilling. Users consistently report the switch away from a flat travel mouse removes the wrist ache within the first week. At Mascom International, we're seeing steady demand from Nairobi tech teams and finance departments buying two and three units at a time. Walk into our Kimathi Street store Monday through Saturday, 9:00 AM to 7:00 PM, or order for pay-on-arrival delivery to any of Kenya's 47 counties.
Questions Kenyan Buyers Ask About the Logitech MX Master 3S
What makes the Logitech MX Master 3S different from a normal office mouse?
Three things: the sensor, the scroll wheel, and the shape. The 8,000 DPI Darkfield sensor is double the 4,000 DPI of the older MX Master 3, so it stays accurate on a 4K monitor where a 1,000 DPI office mouse feels sluggish. The MagSpeed steel wheel free-spins through 1,000 lines per second, then stops on a single pixel. The tilted body holds your wrist at a more natural angle instead of flattening it against the desk. A KSh 1,500 mouse does none of this.
How long does the Logitech MX Master 3S battery actually last?
Up to 70 days on a full charge, from a 500 mAh rechargeable lithium-polymer cell. In practice that means charging it roughly every two months, not every week. If it does run flat mid-task, one minute on the USB-C cable returns three hours of use, and the mouse keeps working while plugged in. For Kenyan offices dealing with power interruptions, this matters: the Logitech MX Master 3S is not a device you have to plan your day around. There are no AA batteries to buy and replace.
Is the Logitech MX Master 3S worth KSh 17,000 in Kenya's market?
For anyone using a computer as their main work tool, yes. Spread over a three-year working life, KSh 17,000 is roughly KSh 16 per working day. Compare that to what a repetitive strain injury costs in physiotherapy visits and lost billable hours. Buyers throughout Kenya tell us the horizontal thumb wheel alone earns its keep in Excel, where wide sheets normally mean dragging a scrollbar. If you only browse and send email, a cheaper mouse is the honest answer.
Will the Logitech MX Master 3S work on my glass desk?
Yes, provided the glass is at least 4 mm thick. The Darkfield sensor bounces light differently from a standard optical sensor, reading the microscopic imperfections in glass rather than needing a textured surface. It also tracks on high-gloss wood, marble, and dark laminate, all common in Nairobi office fit-outs. This removes the mouse pad requirement entirely. Sensitivity between 200 and 8,000 DPI is set in Logi Options+ in 50 DPI steps, so you can tune it to your screen size.
Can the Logitech MX Master 3S connect to my laptop, iPad and desktop at the same time?
It pairs with up to three devices at once and switches between them with a button under the mouse. Connection is by Bluetooth Low Energy or the bundled Logi Bolt USB receiver, with a wireless range of 10 metres. Windows, macOS, Linux, Chrome OS, iPadOS and Android are all supported. With Logi Options+ Flow enabled on Windows and macOS machines, moving the cursor to the screen edge jumps you to the next computer, and copied text or files travel with it.
Are the Quiet Clicks on the Logitech MX Master 3S really quieter for shared offices?
Logitech measures the left and right click at 90% less sound power than the MX Master 3, taken one metre away. The click still gives you firm tactile feedback — you feel it land, you just barely hear it. The MagSpeed wheel is near-silent in ratchet mode as well. In an open-plan Upper Hill office, a Strathmore or USIU library, or a shared flat at 2:00 AM, this is the difference between working and disturbing everyone around you.
Who should buy the Logitech MX Master 3S?
Software developers, financial analysts, architects, graphic designers, video editors, journalists and university students writing long theses. Anyone whose hand is on a mouse for more than four hours daily. The seven buttons carry app-specific profiles in Logi Options+, so the same gesture button can cut a clip in Premiere Pro and switch worksheets in Excel. Field staff who want something pocket-sized should look at the smaller MX Anywhere 3S instead — at 141 grams and 124.9 mm long, this one is a desk mouse.
What comes in the Logitech MX Master 3S box, and does it work with macOS?
The box holds the mouse, a Logi Bolt USB receiver, a USB-A to USB-C charging cable, and user documentation. macOS is fully supported, including Logi Options+ and Flow. Note that Logi Bolt does not work with older Logitech Unifying receivers, so an existing Unifying dongle from a K380 keyboard will not pair this mouse. Mascom International also stocks the Mac-specific colour variant on request. Ask our Kimathi Street team what is on the shelf today.
How does the Logitech MX Master 3S compare to the MX Master 3?
The body, button layout and 500 mAh battery are unchanged. What moved is the sensor, from 4,000 DPI to 8,000 DPI, and the switches, which are now Quiet Clicks. The receiver also changed from Unifying to the more secure Logi Bolt. If you own an MX Master 3 that still works, the upgrade is real but not urgent. If you are buying your first Master Series mouse, the Logitech MX Master 3S is the current model and the one Mascom International stocks.
Technical Specifications
Sensor Accuracy and Tracking Surfaces
- Darkfield high precision sensor rated at 1,000 DPI nominal, so default sensitivity suits standard 1080p monitors.
- Adjustable from 200 to 8,000 DPI in 50 DPI increments, letting you match cursor speed to a 4K display.
- Tracks on glass 4 mm thick or thicker, removing the mouse pad requirement on modern office desks.
- Reads gloss laminate, marble and dark wood surfaces that defeat standard optical sensors on cheaper mice.
- Double the 4,000 DPI ceiling of the MX Master 3, which matters on multi-monitor and high-resolution setups.
- Sensitivity is set per device in Logi Options+, so your laptop and desktop can each keep different values.
Wireless Connectivity and Device Compatibility
- Pairs with up to three devices at once, switched by an Easy-Switch button on the underside.
- Bluetooth Low Energy connection works on any machine with built-in Bluetooth, no USB port consumed.
- Logi Bolt USB receiver ships in the box for desktops without Bluetooth or in high-interference offices.
- Wireless operating range is 10 metres, well beyond the reach of any normal desk setup.
- Supports Windows, macOS, Linux, Chrome OS, iPadOS and Android, covering nearly every machine in a Kenyan office.
- Logi Bolt is not compatible with Logitech Unifying receivers, so older dongles will not pair this mouse.
Battery Capacity and Rapid Charging
- Rechargeable 500 mAh lithium-polymer battery rated for up to 70 days per full charge under normal use.
- One minute on the USB-C cable returns three hours of use, covering an unexpected flat battery mid-meeting.
- The mouse stays fully usable while charging, so a dead battery never stops your work.
- USB-A to USB-C cable is included; any phone charger or laptop USB port tops it up.
- No disposable AA batteries, cutting both running cost and waste over the mouse's working life.
- Battery level is reported inside Logi Options+, giving warning days before the charge actually runs out.
Button Layout and Workflow Customisation
- Seven buttons total: left, right, middle, back, forward, wheel mode-shift and thumb gesture button.
- MagSpeed steel scroll wheel free-spins 1,000 lines per second, then stops precisely on a single pixel.
- SmartShift switches the wheel between ratchet and free-spin automatically based on how fast you flick it.
- Separate thumb wheel handles horizontal scrolling, which saves real time in wide Excel and Google Sheets files.
- Gesture button triggers four actions by holding and moving the mouse, mapped per application in Logi Options+.
- App-specific profiles load different button mappings for Photoshop, Premiere Pro, Excel, Chrome and Final Cut Pro.
Build Quality and Daily Comfort
- Hand-sculpted shape supports the palm and fingers, tilting the wrist away from a flat desk posture.
- Rubberised textured grip on the thumb rest and heel keeps control during long editing or coding sessions.
- Measures 124.9 mm long, 84.3 mm wide and 51 mm tall, suited to medium and large hands.
- Weighs 141 grams, heavy enough to feel planted on the desk without dragging during fine cursor work.
- Graphite plastics use 27% post-consumer recycled material; Pale Gray uses 22%, with FSC-certified paper packaging.
- Right-handed shape only, so left-handed users should discuss alternatives with our Kimathi Street team first.
Software Support and Package Inclusions
- Logi Options+ runs on Windows and macOS, free from logitech.com/optionsplus, and holds every customisation.
- Flow moves the cursor between two or three computers, carrying copied text, images and files across.
- Logi Bolt receiver measures 6.11 mm by 14.4 mm by 18.65 mm and weighs 1.68 grams, staying in the port permanently.
- Model number MR0077 is printed on the underside label, useful when confirming warranty or spare part queries.
- Box includes the mouse, Logi Bolt receiver, USB-A to USB-C cable and user documentation.
