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

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.

I was issued one of these at work and found it to be nice to use, so got one for my home office also. It’s a good size, the key action has a nice bounce and the mouse is functional. Battery wise is a change about once a year for moderate 8 hours a day usage.

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.

Works right out of the box. Installation was simple. Probably should have gotten the next small size, as it is larger than I expected. But I like the key response and the feel of the mouse, so I'm keeping it. Nice, inexpensive keyboard and mouse.

What a difference a keyboard makes!!! This was purchased to replace an older wireless Logitech keyboard that did not have a "print screen" button. The old keyboard functioned very well for many years, but I needed that additional feature. I was not expecting any improvement, other than the additional button. What a surprise when I discovered the touch sensitivity was improved . It's a joy to type with and such a surprise. Logitech makes good wireless mice and keyboards that are very durable and reliable for many years.. I use them on all my computers!

I used a Logitech MK520 keyboard and mouse for years. When I had to bought a new desktop computer, it came with a new keyboard. I used that new one for a while but didn't like it. I ordered the MK540 trying to get something like my obsolete MK520. Unfortunately, I received a keyboard that was warped -- didn't sit flat. I returned that one to Amazon and received a new set the next day! Nothing wrong with this keyboard! Basically, I love it. I love the feel of the keys, the light on the "caps lock key", the wrist rest...everything. I can't think of anything I would change. Thanks Amazon for quickly handling the exchange.

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

I like this keyboard and mouse combo. It works really well and it’s the second time I’ve purchased it. I’ve had my other keyboard and mouse combo for more than 5 years. I was so glad I was able to purchase another set for my other computer. I think the value for the money is good, good keyboard accuracy, functions very well, I haven’t experienced stickiness of keys, it is easy to set up and lightweight.
