Two computers on one desk usually means a work laptop and a personal machine, and the mouse is the first thing people want to share. There are three ways to do it. A button on the mouse that hops between paired computers. Software that lets the cursor slide off one screen onto the other machine's screen. Or a hardware switch that moves the keyboard, mouse, and monitor together.
The first two are mouse features, and this guide sorts the mice that have them by hand and by budget. The third is a KVM, and if you also need a shared monitor or keyboard, that's the answer: start with KVM switch setup for two computers. If you'd rather not buy hardware at all, Mouse Without Borders vs Logitech Flow vs Synergy covers the software route with any mouse.

Easy-Switch vs Flow vs a KVM: Which One You Need
Easy-Switch is a button, usually on the underside of a Logitech mouse, that cycles between up to three paired computers. Press it, the mouse talks to the other machine. It works over Bluetooth or a receiver, needs no software and no network, and it's the feature every mouse in this guide has in some form. The ProtoArc calls its version a mode button; the idea is the same.
Flow is software in Logi Options+. Install it on each computer, put them on the same network, and the cursor slides off the edge of one screen onto the other computer's screen, switching the mouse automatically. Copy text, an image, or a file on the Mac and paste it on the PC. It's the most natural way to run two machines from one mouse, and it needs a Flow-capable Logitech mouse: the MX Master 4, MX Master 3S, Lift, and MX Vertical here all qualify. It also needs IT to allow the software and the network path, which is the usual reason it fails on a locked-down work laptop.
A KVM is a box. It switches the monitor, keyboard, and mouse together, with any mouse you own, and it's what you want when the shared thing isn't just the mouse. The trade is cabling and the occasional window-shuffle when you switch; why a KVM rearranges windows explains that one. For a Mac and a Windows machine on USB-C, best USB-C KVM for Mac and Windows is the shortlist.
The mouse choice, then, is a hand-fit question with one filter: do you want Flow, or is button switching enough?

- Shape
- Flat palm shell
- Hands
- Medium to large, right
- Sensor
- 8,000 DPI on glass
- Power
- USB-C rechargeable
- Warranty
- 2 years listed
- Easy-Switch pairs up to three computers; Flow lets the cursor cross between them and carries clipboard and files.
- Haptic Sense Panel under the thumb gives customizable feedback on shortcuts and actions.
- Actions Ring pops an app-aware shortcut overlay at the cursor.
- MagSpeed wheel free-spins through long sheets and stops on a line.
- USB-C receiver plus Bluetooth; Logitech claims stronger connectivity than the 3S.
Working for it
- Upgraded 8K DPI sensor for precision on any surface including glass
- USB-C charging with fast-charge (1 min = 3 hours use)
- Quieter clicks reduce noise in shared office spaces
Working against it
- Incremental upgrade may not justify cost for 3S owners
- Still right-hand only with no left-hand option
Buy it if
You run a Mac and a Windows machine side by side, you want the cursor to slide between them, and your desk is glass or a busy laminate.
Skip it if
You're left-handed, your hands run small, or your two computers are on networks that can't see each other. Flow needs a shared network.
Instead: Small hands or a sore wrist go to the Lift, which keeps Flow. Flow blocked by IT? The ProtoArc's button switching doesn't need a network.

The MX Master 4 is the default when the two computers are a Mac and a Windows PC on the same desk. Easy-Switch pairs it to three machines, and Flow lets the cursor cross from one screen to the other with the clipboard and files following. The clicks are quiet, the MagSpeed wheel handles long spreadsheets, and the Darkfield sensor tracks on glass, which matters more than it sounds when two laptops crowd one desk and the mouse ends up on whatever surface is left.
New over the 3S: the Haptic Sense Panel under the thumb, the Actions Ring overlay, and a two-year listed warranty against one. Who should skip it: lefties, small hands, and anyone whose IT department blocks Logi Options+ or keeps the two machines on separate networks. Flow can't cross a network it can't see. MX Master 4 vs MX Master 3S settles the version question.

You want Flow and the MX Master shell, and the 3S is sitting clearly below the 4.
Skip it if
The price gap has closed, in which case the 4's longer listed warranty and newer controls are the better buy.

The MX Master 3S does the two-computer job identically: three devices on Easy-Switch, Flow across them, the same 8,000 DPI Darkfield sensor, Quiet Clicks. What it keeps is a physical thumb wheel where the 4 has a haptic panel, and some hands prefer that.
The reason to buy it is price, and it moves. When it sits well under the 4, it's the smarter buy for the same daily experience. When the gap closes, take the 4's longer listed warranty. Check the live price on the card.

You share one mouse across two or three computers and a flat mouse leaves your wrist sore.

The Lift is the answer when you need one mouse across two or three computers and a flat mouse leaves your wrist sore. It's a 57-degree vertical with Easy-Switch across three devices and Flow between a Mac and a Windows machine, sized for small to medium hands, quiet on calls, and sold in a left-handed version.
What it gives up against the MX Master is glass tracking and the button count. What it gives up against nothing is the multi-device job, which it does in full. Large hands should read Lift vs MX Vertical before buying.

The MX Vertical is the Lift's job for medium to large hands: the same 57-degree angle in a taller body, Easy-Switch across three devices, Flow, USB-C charging, and a DPI switch on top. Right-hand only, and the clicks are standard rather than quiet, which matters if the two computers are both on calls all day.

Skip it if
You need the cursor to cross screens, you're on a Mac and rely on side buttons, or your hands are large.

The ProtoArc EM11 NL is here because it solves the two-computer problem without software or a network. A button on the mouse cycles between two Bluetooth devices and one USB-A receiver, so a locked-down work laptop that blocks Logi Options+ is no obstacle. It charges over USB-C, it's a vertical shape sized for hands under 7.5 inches, and it costs a fraction of the Logitech options.
The limits: no Flow, so the cursor doesn't cross screens; the side buttons don't work on macOS; and only the left and right clicks are quiet. For a Windows user with a work laptop and a home PC, it's the cheap, honest way to share one mouse.

For years the M720 Triathlon was the cheap three-device mouse, with Easy-Switch over Bluetooth or a Unifying receiver and two years on one AA. Logitech has discontinued it, and stock now comes and goes at whatever price a third-party seller sets. It stays in this guide because people still search for it.
If you find one at a normal price from a seller you trust, it still does the job. If you don't, the ProtoArc does the same button switching on current hardware, and the Lift adds Flow.

How to Choose a Mouse for Two Computers
- Decide whether you want the cursor to cross screens. If yes, you want Flow, which means the MX Master 4, MX Master 3S, Lift, or MX Vertical, plus Logi Options+ on both machines and a shared network. If a button is fine, every mouse here works, including the ProtoArc.
- Check what IT allows. If your work laptop blocks third-party software or sits on a separate network, Flow won't run. Button switching still will.
- Measure your hand. Wrist crease to middle fingertip. Under 6.5 inches is small, 6.5 to 7.5 is medium, over 7.5 is large. The MX Master shells are medium to large; the Lift is small to medium.
- Decide flat or vertical. A sore wrist points to the Lift or MX Vertical, which keep Flow. Otherwise the MX Master is faster to learn and carries more shortcuts.
- Ask whether the mouse is really the problem. If you also want one keyboard and one monitor to follow you, buy a KVM and any mouse you like. KVM switch setup walks through the wiring.
Frequently Asked Questions
What is the best mouse for two computers?
The Logitech MX Master 4. Easy-Switch pairs it to three computers, and Flow lets the cursor cross from a Mac to a Windows PC with the clipboard and files following. If your wrist needs a vertical, the Lift does the same switching. On a budget, the ProtoArc EM11 NL switches three devices with a button.
What is the difference between Easy-Switch and Flow?
Easy-Switch is a button on the mouse that cycles between paired computers; it needs no software or network. Flow is Logitech software that lets the cursor slide from one computer's screen onto another's, switching automatically and carrying copy and paste, including files. Flow needs Logi Options+ on each machine and a shared network.
Does Logitech Flow work between a Mac and a Windows PC?
Yes. Flow runs in Logi Options+ on both macOS and Windows, and the cursor, clipboard, and files move between them. The MX Master 4, MX Master 3S, Lift, and MX Vertical all support it.
Can I use one mouse on two computers without any software?
Yes, with a mouse that has a switching button. Every Logitech mouse here has Easy-Switch, and the ProtoArc EM11 NL has a mode button that cycles two Bluetooth devices and a receiver. Press it and the mouse moves to the other computer.
Is a KVM switch better than a multi-device mouse?
They solve different problems. A multi-device mouse shares the mouse only. A KVM switches the keyboard, mouse, and monitor together and works with any mouse. If you want the whole desk to follow you between computers, buy a KVM. If the mouse is the only thing you're sharing, a multi-device mouse is simpler and cheaper.
Which multi-device mouse works with a work laptop that blocks Logitech software?
Any of them for button switching, since Easy-Switch and the ProtoArc's mode button don't need software. Flow won't run if Logi Options+ is blocked, so if that's your situation, buy for the button and skip the Flow premium.
Which multi-device mouse is best for a sore wrist?
The Logitech Lift for small to medium hands, or the MX Vertical for larger hands. Both are 57-degree verticals with Easy-Switch across three devices and Flow. Best ergonomic mouse for wrist pain covers the whole vertical field.
