Logitech Wireless Wave Combo MK550 review: This ergonomic keyboard needs better keys

The wave-shaped keyboard isn't for everyone.

Boasting a slightly curved, contoured keyboard and a smooth, substantial mouse, the Logitech Wireless Wave Combo MK550 could be just the thing for typists with aching wrists and tendons, provided you warm to the wave-like form factor.

But while we like the keyboard’s roomy design, padded palm rest and array of programmable hotkeys, we’re disappointed by the cheap feel of the keys themselves, particular given the MK550’s $80 list price (we found it for only $45 on Amazon, though). And while the included mouse feels pleasingly hefty, lefties will be miffed by the righty-oriented button layout.

Note: This review is part of our wireless keyboard roundup. Go there for details about competing products and how we tested them.

Basic features

  • Windows OS support, limited Mac support
  • Wireless 2.4GHz RF connectivity
  • 17 programmable keys
  • 2X AA batteries for keyboard (3 years’ advertised battery life), 2X AA batteries for mouse (2 years’ advertised battery life)


Measuring 19 x 10 x 1.5 inches and weighing about 2 pounds, 3 ounces, the MK500 is one of the biggest keyboards I’ve ever tested. Indeed, if you extend its rear two-step feet to their full height (which props the keyboard up 8 degrees), the keyboard rises to a full 2.5 inches in height—so tall, in fact, that it blocked my keyboard tray from sliding back into my desk. Thankfully, the second of two steps in the retractable feet raises the keyboard only 4 degrees, shaving a half-inch off its overall height.

Besides its imposing height, the MK550 also boasts a padded palm rest. The keyboard itself is both slightly curved and contoured in a wave shape, creating a pair of dips roughly where the A, S, D, F, and J, K, L, and semicolon keys sit. Logitech says its so-called “Comfort Wave Design” is intended to “support the actual, varied lengths of your fingers.” We’ll delve into the actual feel of the keyboard in a moment.

Another attention-grabbing design feature on the MK550 is its array of hotkeys and controls, complete with a central volume toggle surrounded by media playback buttons, prominent buttons for Photo, Music, Windows Media Center (which maps to Groove Music in Windows 10), Settings and Task View, plus a Zoom toggle, hotkeys for Microsoft Word, Excel, Edge, Search, E-mail, and more.

In all, I counted 30 hotkeys on the MK550 (assuming toggles count for two keys), 17 of which can be reprogrammed using Logitech’s aging SetPoint app. The newer, slicker Logitech Options utility works only with the MK550’s bundled mouse—which, as we’ll soon see, comes equipped with its own impressive array of extra buttons.


Both the MK550 keyboard and mouse connect to a PC via a wireless 2.4GHz USB dongle, which plugs in and works instantly without the need for drivers. The MK550’s wireless connection never dropped or sputtered during my testing, and both the keyboard and mouse quickly reconnected after going to sleep following periods of inactivity.

While Logitech says the MK550 will work only with Windows PCs, the keyboard and mouse combo also connected to my iMac. Because there’s no Mac version of Logitech’s SetPoint software, however, Mac users won’t be able to customize the MK550’s hotkeys.

Typing feel

Whether the MK550’s waved keyboard works for you will likely be a matter of taste. I found the contoured design to be a bit gimmicky and distracting, although I’d probably grow accustomed to it over time. That said, the slight curve in the overall keyboard shape does help keep your wrists at a straighter, more comfortable angle. Your experience with Logitech’s Comfort Wave Design may vary, so I’d urge you to try it in person to decide whether it’s a fit.

As for the keys themselves, they’re disappointingly “meh” given the price of the keyboard. While the sculpted design of the keys make for easy discovery, the key caps feel a tad hollow and cheap, and there’s a fair amount of clickity-clack as you type. On the plus side, the MK550’s keys boast a solid, tactile bump in the middle of each keystroke, along with a decently springy rebound.


The 4-ounce mouse that comes bundled in the MK550 package feels great, complete with a pleasing heft, rubberized grips, a smooth scroll wheel and a nice clicking action. In addition to doubling as a middle button, the scroll wheel can also be nudged left or right; by default, scrolling the active page left or right accordingly. Finally, you get two more side buttons, but only on the left side of the mouse, an annoyance for lefties.

Each of the mouse’s buttons (including the left and right scroll wheel clicks) can be programmed via Logitech’s slick Options apps, which serves up functions ranging from switching apps and minimizing windows to launching programs or assigning keystrokes. You can even customize mouse gestures that trigger dozens of possible PC actions.


Big, roomy, hotkey-happy and ergonomically minded, the Logitech Wireless Wave Combo MK550 could be just the ticket for Windows users whose aching fingers need a break. That said, we wish the loud keys on the MK550’s keyboard felt more substantial, while the included mouse is designed mainly with righties in mind.

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

This smart laptop was enjoyable to use and great to work on – creating content was super simple.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries


As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

Taylor Carr


The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
