What “slim” actually means on a keyboard and mouse
Slim isn’t a marketing word I take at face value. It gets used for two very different things. Sometimes it means low-profile keys: shorter key travel, a flatter scissor-switch mechanism, less height off the desk. Other times it just means a smaller footprint: fewer keys, less horizontal desk space, same tall mechanical switches underneath. Both are legitimate reasons to buy, but they solve different problems. For a shallow desk, look at our compact wireless keyboard picks. For a keyboard that looks and feels bulky in front of your monitor, you want genuine low-profile scissor keys, which is what most of the combos here are built around.
The mouse half of the equation matters more than people give it credit for. A slim keyboard paired with a chunky gaming mouse looks mismatched, and more practically, it means managing two charging schedules, two receivers if you skipped a combo, and two separate failure points. That’s the actual case for buying a bundle: one dongle, one battery rhythm, one return window to test both pieces inside.
Bundle or buy separately?
Bundles make sense when you don’t already have strong opinions about your mouse. Setting up a new hire’s desk from scratch? Grabbing the Wave Keys MK670 combo and being done with it is a completely reasonable call: cheap enough that if the mouse turns out wrong for someone’s hand size, you haven’t lost much. But if you already know you like a particular mouse shape, or need a vertical mouse for wrist pain, buying the keyboard and mouse as two separate purchases from our keyboards hub and mice hub gets you a better-matched setup than any combo box will.
There’s also a real case for going smaller still. For maximum desk space back, a wireless mini keyboard paired with any slim mouse frees up more real estate than even the compact combos here. In an open-plan office where click noise from a dozen people typing is genuinely grating, cross-check against our silent keyboard picks. Slim and quiet aren’t the same spec, and a low-profile board can still be a loud one.
The failure pattern I’d actually worry about
You'll notice across ergonomic keyboard reviews that the most common complaint isn't actually about how they feel to type on—it's premature key failure. Amazon's aggregated feedback for the Wave Keys points to a recurring issue where number-row keys stop working after a couple of months of regular use. Rather than just trusting the overall rating, I'd make a point of thoroughly testing that number row and checking both sides of any wireless keyboard during the return period. If you go with a wired model instead, you completely sidestep the wireless connectivity problems that can plague cordless boards, which matters if you prioritize rock-solid reliability over a cleaner-looking desk.
Who should spend more, who shouldn’t
The MX Keys S Combo is what I'd choose if my employer was footing the bill and I wanted to stop fussing with keyboard and mouse choices for the next several years—the included palm rest alone covers a meaningful portion of what you're paying extra. On the flip side, if you're outfitting a handful of new team members on a tight budget, the Wave Keys MK670 clocks in under ninety bucks and works reliably enough that I wouldn't hesitate to distribute them. The Perixx PERIDUO-614US gets you in the door cheapest, and it could actually be solid, though with only around twenty reviews supporting that appealing score, I'd consider it a promising option rather than a guaranteed winner.
One honest note: if wrist pain rather than desk space is driving the purchase, a slim keyboard by itself is a mild intervention at best. Pairing it with a proper wrist rest, or looking at genuinely split ergonomic boards, does more for that specific problem than shaving a few millimeters off key height. Long nails make typing on flat, low-profile keys awkward for some people, so our keyboards for long nails guide covers that tradeoff directly rather than assuming slim is universally better.
How I picked these
I worked from a verified research brief pulling live Amazon prices, ratings and review counts, cross-checked against Amazon’s own aggregated “customers say” summaries for known complaint patterns. I didn’t run these in a lab, measure key travel with calipers, or time anyone’s typing speed. I read the listings, the specs manufacturers publish, and what the review aggregation actually says, then flagged anywhere the sample size was too thin to trust a star rating on its own. Where a figure wasn’t confirmed on a live product page, I left it out rather than guess.
