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

Great value for a great product
I liked this product so much that when we needed another wireless keyboard and mouse combo, I didn’t hesitate to buyer it again! This set was a great price, it is well made and sturdy, the keys have the right resistance and response. It is a matte finish so there is little glare on the keys, and I like that it has both types of keyboards, alphabetical and numerical all on the same keyboard. It is a nice size for having everything built in for home and office use and it sets up quickly with great connectivity. Although it uses batteries, those last a long time so it is economical as well. I am very happy with this purchase and would work with this seller again.

Old Reliable – time for a refresh
Rapid (very rapid) delivery of a good quality keyboard and mouse. I replaced my prior keyboard with this identical keyboard and mouse combination. I use the keyboard and mouse a LOT… constant use every day. After about two years of use, the mouse left-click button starts to fail (creating double clicks when I just click once) and labels on the keys of the keyboard (especially the A and S keys) start to rub off. So, I just order a new keyboard/mouse. Replacing the old keyboard/mouse is very easily done. Just use the Logitech software to remove the old devices and install the new. Process takes under 5 minutes.

Perfect keyboard with wireless Unifying Receiver
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 configurableThe 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.

Well, Logi (Logitech)’s normally great record has been broken…
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. 😀 K

Great keyboard and mouse combo! Easy setup, smooth to use, good quality — and even my cat loves it. Very happy with this purchase!

I’ve always trusted Logitech with many of my peripherals great quality for the price and noticeably longer battery life than most other brands in it’s price range. Sure there are cheaper alternatives some might be better but I’ve noticed the build quality is lacking and some feel like they’d fall apart on the first week you use them. You might pay a little more for the branding but many Logi I’ve owned in the past haven’t failed me yet. I still have one combo hanging around for 15 years now, and still functions excellent except for some discoloration on keys.
