Logitech MK540 Wireless Keyboard Mouse Combo

Buying a keyboard and mouse separately usually means dealing with two different USB ports and two different connection types. It also means two things to keep charged. The Logitech MK540 Wireless Keyboard Mouse Combo skips all of that. It pairs both devices through a single tiny USB receiver, so setup takes seconds rather than minutes.

That receiver uses Logitech’s Unifying technology, giving you an encrypted wireless connection that stays reliable up to 10 meters away. There’s no noticeable lag or dropout, even with regular daily use across a full workday.

The keyboard itself keeps a full size layout, so the transition from any standard keyboard feels immediate rather than something you need to adjust to. A built in palm rest and adjustable tilt legs help with comfort during longer stretches at the desk, and the keys are treated for abrasion resistance, meaning the lettering holds up well over years of typing. It’s also spill resistant, able to handle up to 60ml of liquid without damage.

The mouse matches that same practical approach. Its contoured, ambidextrous shape works equally well in either hand, and soft rubber side grips add a steady, secure feel during use.

Battery life is another strong point. The keyboard runs for up to 36 months on a single set, while the mouse lasts around 18 months, so replacements are rare.
