If you want the MagSpeed electromagnetic scroll wheel, pick the MX Master 4, MX Master 3S or MX Anywhere 3S; the MX Vertical does not have it. All four are on Logitech's list of devices that support Logitech Flow (one mouse across two computers, including Windows and macOS). The receiver is where they differ: the MX Master 4 ships with a USB-C Logi Bolt receiver, the MX Master 3S uses Logi Bolt (in the box only on the Standard Edition), the MX Anywhere 3S works with Logi Bolt but ships without one, and the MX Vertical uses the older Unifying receiver, which is included.
MagSpeed · Flow · compact, receiver not included
See MX Anywhere 3S on Amazon →Three questions decide which Logitech MX mouse fits. Do you want the MagSpeed wheel? Then it is the MX Master 4, the MX Master 3S or the compact MX Anywhere 3S. Do you want Flow, so one mouse moves between two computers? All four mice on this page are on Logitech's Flow list. Which receiver do you need? The MX Master 4 comes with a USB-C Logi Bolt receiver, the MX Master 3S uses Logi Bolt or Bluetooth, the MX Anywhere 3S needs a Bolt receiver bought separately or Bluetooth, and the MX Vertical uses the Unifying receiver it ships with. Every figure on this page comes from Logitech's own product pages, listed under Sources.
This is a research-based comparison, not a hands-on test. We did not use or measure these mice; every spec below is taken from Logitech's own product and software pages, read on 2 November 2026 and linked in the Sources section. Logitech can change a page at any time, so check the listing before you buy.

All four pages give the battery figure with Logitech's note that battery life may vary based on user and computing conditions. A dash means we did not find the figure on the page we read.
MagSpeed is Logitech's electromagnetic scroll wheel. Logitech's MX Master 3S page says it is "precise enough to stop on a pixel and quick enough to scroll 1,000 lines per second". The MX Master 4 and MX Anywhere 3S pages describe the same two modes: a ratchet mode for line-by-line scrolling and a hyper-fast free-spin mode. Both pages say the wheel is 90% faster than a regular Logitech mouse (the MX Master 4 page specifies one without an electromagnetic scroll wheel). Both also claim 87% more precision, but against different baselines: the MX Anywhere 3S page compares with a regular Logitech mouse, while the MX Master 4 page compares with the MX Master 2S (Logitech Options installed, Smooth scrolling enabled).
Of the four mice here, the MX Master 4, MX Master 3S and MX Anywhere 3S have MagSpeed. Logitech's MX Vertical page does not describe a MagSpeed wheel. The MX Vertical is built around a vertical grip instead.
Logitech's Flow page says Flow lets you "seamlessly work between two computers - even across Windows and macOS": you move the cursor of a Flow-supported mouse to the edge of the screen to cross to the other computer, and you can copy text, images and files on one computer and paste them on the other. A Flow-supported keyboard follows the mouse.
Logitech's setup has three steps:
The Flow page's featured supported devices include the MX Master 4, MX Master 3S Bluetooth Edition, MX Anywhere 3S and MX Vertical, and also the MX Ergo S and Lift. So for this group, Flow does not separate the models. All four support it. What separates them is the wheel and the receiver.
Two Logitech USB receiver types show up in this group. The three MagSpeed mice use Logi Bolt, and Logitech's spec sheets say the MX Master 3S and MX Anywhere 3S do not work with Unifying receivers. The MX Vertical ships with a Unifying receiver. Here is how it works out per model, according to each model's Logitech page:
Logitech lists a USB-C Bolt receiver in the box and says the mouse is "compatible with both USB-C and USB-A receivers". It also connects over Bluetooth Low Energy 5.1. Logitech's page notes that the USB-C charging cable is not included.
See MX Master 4 on Amazon →Logitech's spec sheet lists the Logi Bolt USB receiver as included "Only for Standard Edition" and says the mouse is "Not compatible with Logitech Unifying USB Receiver technology". Logitech's US store currently sells the Bluetooth Edition, whose box lists only the mouse and user documentation. The Amazon listing we link is titled as the version with a Bolt receiver. If you need the dongle, check the box contents on the listing before you order.
Our MX Master 3S review → · MX Master 3S vs MX Master 3 →
See MX Master 3S on Amazon →Logitech says the MX Anywhere 3S connects to up to 3 devices via Bluetooth and is "Compatible with Logi Bolt USB receiver only (receiver not included)". It is not compatible with other Logitech USB receivers. The box holds the mouse, a USB-A to USB-C charging cable and documentation.
MX Master 3S vs MX Anywhere 3S →
See MX Anywhere 3S on Amazon →Logitech lists three ways to connect the MX Vertical: the Unifying receiver, Bluetooth Low Energy, and the USB-C charging cable. The box holds the mouse, a Unifying USB receiver, a USB-A to USB-C cable and documentation. If you already run other Unifying devices, this is the one that shares their receiver type.

“Logitech MX Master 4 vs MX Anywhere 3S: Which to Buy?” from the Adam Talks Tech channel. The spec table on this page comes from Logitech's own pages, not from this video.
You want MagSpeed and a receiver in the box: MX Master 4, which ships with a USB-C Bolt receiver. The MX Master 3S Standard Edition also includes a Bolt receiver, so check which edition a listing is.
You want MagSpeed in a smaller mouse: MX Anywhere 3S. Plan on Bluetooth, or buy a Logi Bolt receiver separately.
You already use Unifying devices: MX Vertical is the only mouse here that uses Unifying. The MX Master 3S and MX Anywhere 3S state that they do not work with Unifying receivers.
You mainly want Flow: any of the four. Logitech lists all of them as Flow-supported. Setup is the same: Logi Options+ on both computers, a different channel per computer, and the same network.
For a broader ranking that includes non-Logitech options, see our best wireless productivity mouse guide.
Of the four MX mice compared here, the MX Master 4, MX Master 3S and MX Anywhere 3S have the MagSpeed electromagnetic scroll wheel, which Logitech rates at up to 1,000 lines per second. Logitech's MX Vertical page does not describe a MagSpeed wheel.
Logitech's Flow page lists the MX Master 4, MX Master 3S Bluetooth Edition, MX Anywhere 3S and MX Vertical among its featured supported devices, alongside other models such as the MX Ergo S and Lift. Flow needs Logi Options+ on both computers, the mouse paired to each computer on a different channel, and both computers on the same Wi-Fi or Ethernet network.
Logi Bolt or Bluetooth. Logitech's spec sheet says the MX Master 3S is not compatible with Logitech Unifying receiver technology, and lists the Logi Bolt USB receiver as included only with the Standard Edition. The Bluetooth Edition that Logitech's US store sells lists only the mouse and documentation in the box.
The MX Master 4. Logitech lists a USB-C Bolt receiver in the box and says the mouse is compatible with both USB-C and USB-A receivers. Logitech also notes the MX Master 4 charging cable is not included.
