Quick verdict
The Logitech M720 is the better-value office mouse. It gives you three-device switching, Bluetooth, a USB receiver, a dual-mode scroll wheel, horizontal tilt scrolling, and a replaceable AA battery without charging a premium for controls you may never use.
The Logitech MX Master 3S is the better-equipped primary desk mouse. Its dedicated thumb wheel, MagSpeed main wheel, quieter clicks, 8,000 DPI sensor, and USB-C charging are meaningful upgrades for wide spreadsheets, creative timelines, high-resolution displays, and shared workspaces.
Do not choose on the assumption that the M720 is a tiny travel mouse or that the MX Master 3S is dramatically heavier. Logitech lists them at 135 g and 141 g respectively. The real decision is whether the MX Master 3S’s extra controls and quieter operation are worth its higher price.

Choose the Logitech M720 if value and simple power matter most
The M720 is not merely a basic mouse. Its main wheel switches between precise ratcheted scrolling and free-spinning hyper-fast scrolling. Tilting that wheel can move horizontally, and the mouse can switch among three paired devices. Those features cover the core needs of email, documents, web work, and ordinary spreadsheets.
Its most practical advantage is the power system. One replaceable AA battery avoids a charging schedule, and Logitech rates the battery for up to 24 months. When it eventually runs flat, a fresh cell gets the mouse running again immediately. That makes the M720 sensible for shared desks, secondary computers, and equipment pools where nobody wants responsibility for charging another device.
The trade-off is control precision rather than basic capability. The fixed 1,000 DPI sensor is adequate for standard office displays, but it gives you no sensitivity range to tune for a 4K monitor or a very large multi-screen desktop. Horizontal scrolling also shares the main wheel instead of getting its own thumb control.
Choose the MX Master 3S if its controls match your daily work
The MX Master 3S earns its premium through controls that can reduce repeated navigation. Its MagSpeed wheel switches between precise and free-spinning behavior, while a separate thumb wheel handles horizontal movement. That is useful in wide spreadsheets, video or audio timelines, design canvases, and any workflow where left-to-right navigation is routine rather than occasional.
Its Darkfield sensor adjusts from 200 to 8,000 DPI in 50-DPI steps. Logitech also specifies tracking on glass at least 4 mm thick. That flexibility matters more on high-resolution displays and unusual desk surfaces than it does on a conventional 1080p office setup.
Quiet Clicks are the other clear upgrade. Logitech measures them against the earlier MX Master 3 and claims 90% less click noise while retaining a tactile feel. That does not make the mouse silent, but it gives the 3S a documented advantage in shared rooms and during calls.
The current black Amazon listing linked here is a Bluetooth model whose page says a Logi Bolt receiver is not included. Other MX Master 3S packages may include one, so check the exact listing contents if you need USB-receiver connectivity rather than Bluetooth.
Size, weight, and hand fit
The MX Master 3S is larger in every dimension: about 10 mm longer, 10 mm wider, and 6 mm taller. The difference should be considered as a shape and hand-fit question, not a large weight penalty. At 141 g, the 3S is only 6 g heavier than the 135 g M720.
Both mice are sculpted for right-handed use. The M720’s smaller footprint may suit a smaller hand or a crowded desk, while the MX Master 3S gives a larger hand more surface area. Those are fit tendencies, not guarantees. Mouse comfort depends on hand size, grip style, desk height, and how much of the forearm is supported.
Neither model is a strong choice for a left-handed user, and neither should be treated as an ultralight travel mouse. If low carrying weight is the priority, compare genuinely compact models rather than choosing between these two on a misleading weight assumption.
Scrolling and spreadsheet work
Both mice can move quickly through long documents. The distinction is how much control you get around that movement.
The M720’s dual-mode wheel is already a substantial step above a simple ratcheted wheel. Pressing the wheel-mode button changes between click-to-click and free-spin behavior, and wheel tilt provides horizontal scrolling. For occasional wide sheets, that is enough.
The MX Master 3S separates the jobs. Its main MagSpeed wheel handles vertical movement and its thumb wheel handles horizontal movement. If you spend hours in wide workbooks, timelines, or design tools, keeping horizontal control under the thumb is the strongest reason to pay more. If horizontal movement is rare, the M720’s tilt wheel preserves most of the useful function at lower cost.
Multi-device switching and receiver compatibility
Both models pair with up to three devices and let you switch among them. Both support Bluetooth. Their USB receiver systems, however, are different.
The M720 uses Logitech Unifying. The MX Master 3S uses Logi Bolt. A Unifying receiver cannot pair with a Bolt-only mouse, and a Bolt receiver cannot pair with a Unifying-only mouse. This matters if you already have Logitech peripherals and expect one dongle to serve all of them.
The MX Master 3S also supports Logitech Flow through Logi Options+, allowing compatible computers to share pointer movement and transfer supported content between systems. Treat that as a software-assisted workflow feature, not the same thing as the hardware button used to change the active device.
Before buying, inventory the receiver logos already on your desk and check the package contents of the exact SKU. Bluetooth can avoid the dongle issue, but managed work computers sometimes restrict Bluetooth or software installation.
AA battery versus USB-C charging
The M720’s replaceable AA battery favors long intervals and instant replacement. Logitech’s up-to-24-month figure is a rating, not a promise, but it establishes the intended low-maintenance role.
The MX Master 3S’s rechargeable battery favors a fixed workstation. Logitech rates it for up to 70 days on a full charge and up to three hours of use from a one-minute quick charge. It can operate while connected by USB-C, so a flat battery does not require you to stop working if a cable is available.
Neither approach is universally better. Choose the M720 if you prefer keeping spare batteries and not thinking about cables. Choose the MX Master 3S if you prefer rechargeable hardware and already keep USB-C within reach.
What the price difference actually buys
The MX Master 3S premium buys four concrete upgrades: a dedicated thumb wheel, adjustable high-resolution tracking, quieter primary clicks, and rechargeable power. Its larger shell and software features may also suit a permanent workstation, but shape and software are more personal than the hardware differences.
The M720 is the rational default when those upgrades do not map to a repeated task. It already has fast scrolling, wheel tilt, programmable controls, Bluetooth, receiver connectivity, and three-device switching. Paying more does not improve value if the thumb wheel and sensor range go unused.
The MX Master 3S becomes easier to justify when horizontal navigation happens throughout the day, click noise is a real constraint, or high-resolution tracking reduces the effort of crossing a large display. In those cases, the extra features are tools rather than decoration.
Better buy: M720 for value, MX Master 3S for specialist control
Buy the Logitech M720 if you want the lower-cost route to capable multi-device office work, prefer a replaceable AA battery, or need compatibility with existing Unifying accessories.
Buy the Logitech MX Master 3S if this will be your primary right-handed desk mouse and you will regularly use its thumb wheel, quiet clicks, adjustable 8,000 DPI tracking, or USB-C charging.
The M720 is the better value for most routine office workloads. The MX Master 3S is the better tool for workflows that can name the premium feature they need.
