MK540 Advanced Wireless Keyboard and Mouse Combo for Windows, 2.4 GHz Unifying USB-Receiver, Multimedia Hotkeys, 3-Year Battery Life, for PC, Laptop

The Logitech MK540 combo is excellent for everyday use. The keyboard is full-sized and comfortable to type on, with quiet, responsive keys. The mouse is simple but works well, and both have impressive battery life. Setup is easy with wireless receiver and the build feels solid. Perfect for a home or office productivity.

I’ve been using the Logitech MK540 combo for a while now, and overall it delivers very good value for the price. For what you pay, you get a full-size keyboard with a number pad, dedicated media keys, and a comfortable mouse that works exactly as it should right out of the box. The wireless connection is stable, the keys respond reliably, and the mouse tracks smoothly on most surfaces. It’s the kind of setup that just quietly does its job without any fuss. That said, there are a couple of trade-offs that come with the budget-friendly price. The materials feel a bit on the cheaper side, especially compared to Logitech’s higher-end lines. Nothing feels like it’s going to break, but the plastics don’t have that premium weight or finish. Another drawback is that the combo does not support Bluetooth, which means you’re locked into using the included USB receiver. Not a dealbreaker for a desktop setup, but it’s something to keep in mind if you’re short on ports or prefer Bluetooth for laptops or tablets. Overall, if you’re looking for an affordable, reliable keyboard and mouse combo that performs well for everyday use, this one is a solid pick. Just be aware of the lighter build quality and the lack of Bluetooth before buying.

I like the feel and functionality of the keyboard. The wrist/hand resting platform is little deep for my liking but it’s ok.

I have used this keyboard and mouse for about a month plugged into an Alienware 19 inch laptop on Windows 10 with all updates installed. Only issue with this wireless keyboard is the lack of function for two of the most basic keyboard shortcuts. Ctrl+C and Ctrl+V for copy and paste. Surprisingly the Ctrl+Z and Ctrl+S shortcuts work. Spent over an hour on chat with tech support at Logitech without finding a solution. Eager, friendly and worked with me in a gracious manner, but unable to find a solution. I am able to left click and select these windows functions from a menu, but I have used keyboard shortcut for so many years it feels awkward. I have uninstalled the software Logi Plus, cleaned my registry of all traces of their software and did a clean install with no change in behavior. Still trying to decide if I will dump this and find another keyboard.

I've tried and had to return multiple $100+ keyboards due to irregular F1-F12 or arrow key layouts, dreaded Fn key in the lower-left, mushy key travel feel, etc. I've been using exclusively Logitech keyboards & mice since the 90's, but gave up and tried venturing to other brands like Keychron (had issue with inadvertent key presses when pausing fingers over keys). But this simple keyboard just gets it right. I didn't even need the bundled mouse since I use Logitech MX Master 2S, but like that I can use the same Logi Unifying Receiver and Options+ software (optional). There are dedicated keys: * power on/off colored slider * play/rewind/ff * volume mute/down/up * calculator * battery level * 2 user-configurable buttons * Fn+ F1-F8 are also configurable The are 3 height levels, built-in mini palm rest (I still use a big keyboard mat beneath), slot for Unifying Receiver and 2 AA under the battery cover. Minor issue is the batteries clack when using the F5-F12 keys (just below where the batteries are), but I taped a little strip of foam on the inner side of the battery cover to resolve it. Also great is Logitech MK270, which is more compact, light, and perfect for the road. Both have amazing battery life.

Gotta vent. I've had my Logitech K800 forever and a day and LOVED it. Never any performance problems, smooth, comfortable, easy to use, and took a beating daily for years. Got it through work, so it was more expensive than your usual, but it couldn't last forever. It started being unable to take a charge, so I knew I would have to retire it. (They stopped making these (WHY???) and they're selling after-market for a fortune.) I have Logi all things keyboard, mouse, etc., so went with them again. Bought a K650, but out of the gate, it started doing weird stuff, like repeating keys when you weren't even touching the keyboard, jamming up, or just stopping functioning. Did all the usual troubleshooting, but nothing worked. Just to save time, I sent it back here and replaced it with an MK540. Son of a gun if it didn't start immediately doing the same things. NOW I was cranky, so I did my online research and learned these are well known problems for others, who also couldn't solve them. I then went to Logi tech support. Got a level 1 person who walked me through the standard steps I'd already done multiple times (Did you turn it off and on again? :-D), gave me long lists of things to try, then at the end, when nothing worked said, "Well, it's within 30 days so just return it to the seller, and here's a link to our other keyboards." "Ummm," I said, "this is the exact same circumstance with two DIFFERENT keyboards in a row. As I had no trouble with my previous Logi keyboard, and nothing else has changed on my end, it seems logical that the problem is with the new software, hardware or some QA problem with producing these models. Why would I go buy another one when we don't know WHY it's doing this, suggesting I could go through this all over again?" (BTW, a MAJOR inconvenience for days). Her answer (twice): "Don't worry, it'll be fine, just go get another one." OMG. Stubborn, so I gave it a third shot (MX Mechanical) now for 3x the money hoping better quality would help, but guess what? I've now received my 3rd notice from Amazon saying delivery will be delayed, this time with no date estimate known. I tried, Logi, but even I am done. Buying a highly rated other keyboard that has all the features I need. Logi, not sure what you're doing with these membrane ones (vs. mechanical), but it's not working. If you could ship me a K800, I'd so appreciate it. :-D K

The keyboard feels great, nice and quiet but still has a good "click" to the keys. It’s been really comfortable thanks to the wrist rest. The mouse is ok. Nothing super fancy, but it feels good in the hand, tracks well, and just works. Not really a gaming mouse, but totally fine for everyday stuff.

Always buy this to replace the beige crap pried off an Apple II that I normally get at the office. Mouse is sized for a normal adult hand, and goes both ways.(Apologies to any North American government obsessed with rolling back human rights). If you are the type (see what i did there?) who still double space after a period this is a good solid option.

Thus far no complaints. The keyboard and mouse are comfortable for daily office use. Have not experienced any lag issues so very pleased with that. Connectivity was seamless. Only complaint, very minor, is that there is no light or indicator to show when the “number lock” is on/off. I really thought this would be a standard feature in 2025. There is however an indicator light for “caps lock”.

Too bad mk800 was discontinued, i miss the backlit. Having said that, for the price, this combo is an excellent solution. Im still using a better Logitech mouse, and took a minute to figure out how to connect the kb (had to download and install Logitech software). So far quite happy !

The keyboard is great. Very versatile and easy to use. The only drawback is that the keyboard is heavier on the left-hand. It is heavier on the right side due to the numerical keys present. When you're using it, it tends to slide easily upwards on the left than on the right and the keyboard is then crooked or if you hit it slightly it takes off on the left side.
