Customer Ratings & Reviews

I was about to return this set due to the EXTREME lag issue and poor Bluetooth connectivity reported by some others. Both the mouse and keyboard were unusable, it was that bad. However I was able to troubleshoot it and resolve the problem by taking the following two steps: - Download the Logitech Options automatic driver update software from the Logitech website. Simply look up the MK540 product, scroll all the way to the bottom and click the "get support" button. Then click on "downloads". Select your OS version and install the software. - On your PC tower, switch the USB port that the unifying receiver is plugged into and see if that fixes the issue. I have an older model Logitech wireless set hooked up to a different PC that was laggy once in a great while and my husband discovered that the USB port itself was failing or damaged. A simple fix but effective. It seems like the majority of people who purchase this set don't have to do this and are able to just plug and play, but give these two fixes a try if you run into the dreaded lag issue. The set itself has a pretty good feel, although the keyboard action is a little soft for my taste. My only complaint about the mouse is that it does not have a smooth wheel scrolling option. It's a great value when on sale though and definitely worth the price when working correctly.

Fantastic keyboard - super comfortable and easy to set up!

Already trashed this purchase! Keyboard was never synced and only typed 10% of the time. Went through all of the Logitech site recommendations - nothing worked! Buy a wired setup.

I bought the MK540 to replace an older MK530. After 6 years the batteries had started to leak in the keyboard to the point that the contacts had fallen apart. So I set out to buy the same setup since I liked the 530 so much. But then I found out Logitech had come out with a successor to the 530. The MK540 has better keys with better feed back and raised surfaces that make typing easier. The other functions are the same as the 530 but the buttons are just modernized. So overall the MK540 is a good keyboard as it does what I need it to do.

Perfect keyboard for my business. Keys aren't loud when pressed but I like the way they feel. Mouse is comfortable too. Extremely easy to set up with whatever computer you're using. 11/10

Very user freindly. All features easy to use. I would recommend this product.

Was hesitant to buy this because it said it was not Mac compatible. So far, I've had no issues with either the mouse or keyboard on my iMac. I'm using an older iMac model with the traditional USB inputs. I rarely use Mac keyboard shortcuts, but the ones I do use work fine on this keyboard. For common Mac key commands using the command key, you instead use the Windows key in the lower left. The keyboard itself is a huge improvement for me over the Mac wireless w/o numpad--I much prefer the more tactile keys for work, and the option to elevate the keyboard with the legs in the back make it much easier on my wrists. The numpad is also a huge bonus. I've had zero issues with wireless connectivity. The mouse is wonderful, very ergonomic and I love having the wheel. It was easy to change Mac settings from the natural scroll used with Mac mice to the conventional scroll for traditional mice with scroll wheels. Definitely go with this if you're wanting to upgrade to a more tactile keyboard with a numpad + a nice mouse, and don't want to shell out 100+.

Easy setup. Just plugged in the USB to a port and the mouse and keyboard and was recognized. Nice quality for the price!

This is the first time I've owned a wireless keyboard. I love it

Upgraded to this after I poured a whole 16oz glass of H2O on my Logitech - MK320 this morning ;-( It took me a minute to decide to spend the extra $$ but as I write this review on it I am ecstatic that I did. The texture of the keys and the mouse are velvety smooth and soft. The response time is much faster than the cheaper models. The soft touch mechanical keyboard is quiet and smooth , tactile typing with a minimum of clickity-clack. So far it's great for the price and style. It is soft touch so you don't have to hit the keys hard at all to type. I honestly love it, I can't wait to get to writing!!! Typical Logitech goodness at your fingertips. Go try you just might like it!

Works great, and I love the "touch" of the keyboard.

Excellent quality. Easy to use by any age. Clear lettering

Great keyboard! Easy to read and soft to the touch, so no need to pound on the keys!

Wonderful! This combo is perfect for your wireless needs!

good. easy to use. comfortable on hands/wrists. would recommend

Comfortable keyboard. Helps when I'm writing lengthy documents.

Not sure if the keyboard works because the tower was not working.

Quite keys, easy set up and rapid response for everything.

The price was reasonable. The feel of the keys is awesome. The size of the keyboard is perfect for my desk space. Being able to walk away from my desk with my keyboard and mouse is awesome. The overall function of the keyboard and mouse is great!

I love this keyboard and all of the different features that comes with it. It's a must have ...
