Logitech MK345 Comfort Combo Review (2026): Simple, Quiet

This Logitech MK345 Comfort Wireless Keyboard and Mouse Combo review looks at one of the more straightforward desk setups you can buy: a full-size keyboard with a number pad, a contoured right-handed mouse, and a single USB receiver that handles both. It sits in the mid-range part of the market, and it has been recommended in 5 expert buying guides. It is aimed at people who want a comfortable, low-maintenance combo for the home or office and don't need extras.

This review is based on Logitech's published specs and on what independent expert reviews report. It is not based on hands-on testing.

Design and build: built around the palm rest

The MK345's main design idea is comfort for long typing sessions. The keyboard is full-size, with a number pad and a generous integrated palm rest. It measures 17.6 x 7.4 x 0.8 in (447 x 188 x 20.3 mm) and weighs 21 oz (603 g). That is a sizeable footprint, so check your desk space, but it is the usual trade-off for a number pad and a proper wrist rest. Adjustable tilt legs let you change the typing angle.

The mouse is a contoured right-handed design with a natural grip. It measures 4.1 x 2.7 x 1.5 in (105.4 x 67.9 x 38.4 mm) and weighs 3 oz (86.4 g). It uses an optical sensor at 1000 dpi and has 3 buttons. That is a basic layout with no extra programmable buttons listed, which suits everyday office, browsing and document work.

The finish is black. Logitech also says the plastic parts include recycled plastic, which some buyers will like.

Features and what they mean day to day

Quiet typing and media keys

Quiet typing is one of the keyboard's listed features, and reviewers praise it. That matters in shared offices, in open-plan homes, or if you type late while someone else is nearby. The keyboard also has 12 F-keys with easy-access media controls for mute, volume and play. You can adjust playback and sound without opening a window or reaching for the mouse. That is handy for video calls and background music.

Spill resistance

The keyboard is spill-resistant. That is not a reason to be careless with drinks, but it adds some peace of mind on a desk where coffee lives.

Plug-and-play connection

Both devices connect through a single 2.4 GHz USB receiver, with a range of up to 10 meters (33 feet). Setup is meant to be as simple as plugging in the receiver and switching both devices on. Each has its own on/off switch, so you can save battery when travelling or leaving the desk for a long time. Batteries are included, so it can be used straight out of the box.

The listed compatibility is Windows 10/11 or later and Chrome OS. If you use another operating system, check Logitech's support pages before buying.

Battery life, range and connectivity

Battery life is a headline strength. Logitech lists 36 months for the keyboard (2x AAA, included) and 18 months for the mouse (1x AA, included). In practice, you are unlikely to think about batteries for a long time, which fits a combo built to be low-maintenance. Reviewers praise this too.

Connectivity is where the MK345's simplicity becomes a limit. It uses a USB receiver only and has no Bluetooth. The receiver therefore takes up a USB-A port. On a desktop with plenty of ports that hardly matters. On a slim laptop with few ports, or one that has only USB-C, it may be a real annoyance. Without Bluetooth, you cannot pair the keyboard or mouse directly with a tablet or phone.

Some users report occasional lag or connection drops. This is not described as universal, but it is worth knowing about.

What experts like and what they criticise

Reviewers' praise is consistent and focuses on practical comfort rather than flashy features:

• The full-size layout with number pad and a generous palm rest.
• The very long battery life of both devices.
• Quiet typing and easy-to-reach media keys.
• Simple setup and a range of up to 10 meters (33 feet).
• The spill-resistant keyboard, adjustable tilt legs and included batteries.

The criticisms are just as consistent, and the missing features are worth weighing:

• There is no Bluetooth, so the receiver occupies a USB-A port.
• There is no backlight, which makes typing harder in dim rooms.
• The mouse is right-handed only, and can feel small for larger hands.
• Some users report occasional lag or connection drops.

The lack of a backlight and of Bluetooth rules the MK345 out for some uses. If you work in low light or want one keyboard for a PC and a tablet, look elsewhere.

Logitech MK345 Comfort Wireless Keyboard and Mouse Combo review: who it's for

Who should buy it

The MK345 suits home-office workers, students and general desktop users who spend a lot of time typing and want something quiet and comfortable. The number pad helps with spreadsheets and data entry. The media keys help anyone who has video calls or music playing all day. It also suits shared or family computers, where a long battery life and a simple setup mean fewer problems. A spill-resistant keyboard is a sensible choice for a busy desk.

It also makes sense if you want to set up a desk quickly. Plug in the receiver, switch the devices on, and you are working. If you are building out a more comfortable workspace, our guide to the best office chairs covers the seating side.

Who should skip it

Skip it if you need Bluetooth, for example to connect a tablet or a laptop with few ports. Skip it if you often type in dim rooms and want a backlit keyboard. Left-handed users should look elsewhere, because the mouse is right-handed only. People with larger hands should also be wary, as reviewers say the mouse can feel small. If you want a compact keyboard that is easy to carry between locations, the full-size layout and its footprint will probably work against you.

How it fits in its category

The MK345 is a basic, long-lasting, plug-in-and-go combo. Its appeal is comfort, quiet typing and very long battery life rather than extra features. If those are your priorities, it is a good fit. If you want Bluetooth or a backlight, look at other options first.

Verdict

The MK345 does a few things well: a full-size layout with a proper palm rest, quiet keys, convenient media controls and battery life measured in years rather than months. Those strengths suit people who sit at a desk all day and would rather not think about their peripherals. The compromises are just as clear: USB receiver only, no backlight, a right-handed mouse that may feel small, and some reports of lag or dropouts. If your needs match its strengths, it is an easy recommendation. If they don't, those missing features are likely to matter every day, so choose a different set.
