If you bounce between two computers all day like I do, the single biggest quality-of-life upgrade isn't a faster CPU or a fancier monitor, it's a keyboard and mouse that follow you between machines without missing a beat. That's exactly why I went hunting for the best keyboard and mouse for multiple devices, and after living with the Logitech MK850 Performance combo in daily use, it's the one that earned a permanent spot on my desk.
I run a custom-built Windows PC for most of my heavy lifting and a Mac desktop for other projects, and I'm constantly flipping between them. The MK850 lets me jump from one to the other with a single key press. No re-pairing, no unplugging dongles, no shuffling a second set of peripherals around. That alone changed how I work.
Why a multi-device combo matters
Most people who own two computers end up with two keyboards, two mice, and a permanently cluttered desk. I did that for years. The problem isn't just the clutter, it's the friction. Every time you switch machines, you reach for a different mouse with different sensitivity, a keyboard with a slightly different layout, and your muscle memory takes a hit.
The MK850 solves this with Logitech's Easy-Switch system. The keyboard pairs with up to three devices and the mouse pairs with up to three as well, and you flip between them using dedicated buttons. In my setup, button 1 is my Windows PC over the bundled USB receiver and button 2 is my Mac over Bluetooth. Tapping the button reconnects in about a second, fast enough that I don't think about it anymore.
Design and build
This is a full-size keyboard in the truest sense, number pad, function row, the works, finished in a graphite color that disappears into a desk setup rather than shouting for attention. It's a membrane keyboard, not mechanical, so if you're chasing clicky switches this isn't your board. But that's a deliberate trade-off in favor of quiet, comfortable typing, and Logitech nailed the comfort part.
The keys are concave and the keyframe is gently curved, so your fingers naturally settle where they should. The standout feature for me is the oversized, cushioned palm rest. It's integrated rather than a separate accessory, and after long writing sessions my wrists genuinely feel better than they did with my old flat keyboard. There are adjustable tilt legs underneath to dial in the angle, which I appreciated once I found my preferred position.
The mouse is a large, contoured, right-handed design with a soft rubber surface. If you have smaller hands or you're left-handed, take note, this is unapologetically a big right-hand mouse. For my hand it fits like it was molded for it, and the rubber coating makes it easy to grip without feeling slick.
The switching experience
This is the headline feature and the reason I bought it, so let me be specific about how it actually performs day to day.
When I tap the Easy-Switch button to move from Windows to Mac, both the keyboard and the mouse can follow. Reconnection is quick and consistent, I rarely wait more than a beat. I've had this combo running for months and I genuinely can't remember the last time a switch failed or hung. That reliability is what separates a gimmick feature from one you build your workflow around.
What makes it even better is that Logitech configured the keyboard to play nicely with both ecosystems. The modifier keys are labeled and mapped so you're not constantly second-guessing whether you need Cmd or Ctrl, and the layout works correctly on macOS, Windows, and ChromeOS. Switching from a Mac shortcut mindset to a Windows one is still on me, but the keyboard itself never gets in the way.
Customization with Logitech Options
The MK850's hidden depth is in Logitech's Options software. Once you install it on each machine, you can remap buttons on both the mouse and the keyboard to create custom shortcuts, and your configuration is tied to the device you're using.
I set up custom buttons on the mouse for things like switching desktops and triggering app-specific shortcuts, and I assigned keyboard shortcuts that speed up my repetitive tasks. Because the software runs on both my PC and Mac, I can tailor the behavior to each operating system, a button can do one thing on Windows and something more useful on the Mac. For anyone who lives in their tools all day, this is where the real efficiency gains come from.
Logitech also offers a DuoLink feature through Options that links the keyboard and mouse together for smarter navigation, for example, holding the Fn key on the keyboard changes what the mouse does. It's the kind of power-user touch that you don't notice in a spec sheet but start to rely on once you've set it up.
Everyday performance
The mouse's hyperfast scroll wheel is one of those features I didn't think I needed and now won't give up. Flick it and it free-spins, letting me fly down long documents and web pages in an instant, then switch back to ratcheted clicks for precision. As someone who scrolls through long articles, code, and spreadsheets all day, this saves a surprising amount of effort.
Tracking is optical and accurate across the surfaces I've thrown at it. It's not a gaming mouse, there's no ultra-high DPI sensor or featherweight chassis, but for productivity work it's smooth and precise.
Typing is quiet and comfortable for hours, which matters more than I expected. The membrane keys have a soft, cushioned feel rather than a sharp tactile bump, so late-night sessions don't annoy anyone else in the house.
Battery life has been a non-issue for me. The combo is battery powered and rechargeable, and I top it off rarely enough that I've stopped tracking it. That's exactly how peripherals should behave, invisible until you need them.
✓ Pros
- ✓ Instant, reliable switching between up to three devices on both keyboard and mouse
- ✓ Genuinely comfortable full-size keyboard with a great cushioned palm rest
- ✓ Works correctly across Windows, macOS, and ChromeOS with proper key mapping
- ✓ Hyperfast scroll wheel is a real productivity boost
- ✓ Deep customization and DuoLink via Logitech Options
✕ Cons
- ✕ Membrane keys won't satisfy mechanical keyboard fans
- ✕ Mouse is large and right-handed only
- ✕ Takes desk space, this is a full-size board with no compact option
Who it's for
If you regularly work across two or three machines, especially a Windows and Mac combo like mine, this is close to the ideal setup. It's also a strong pick for anyone who wants an ergonomic, comfortable keyboard for long workdays and values quiet typing.
If you're a mechanical keyboard devotee, a left-handed user, or you need a compact, travel-friendly board, this isn't the right fit. And gamers chasing the lowest latency and highest DPI should look at dedicated gaming gear instead.
For me, though, the MK850 hits the exact target it's aiming at: a comfortable, reliable, multi-device combo that makes working across machines effortless.
Verdict
The Logitech MK850 is the keyboard and mouse I actually use every single day, and that's the highest praise I can give a piece of gear. The switching is fast and dependable, the comfort is real, and the customization through Logitech Options lets me bend it to my workflow on both my Windows PC and Mac. It's not a mechanical keyboard and it's not for lefties, but if your goal is a seamless multi-device experience, this combo delivers.
