Keys have a nice feel and touch. Responsive. Good battery life. Numeric pad is as comfortable as calculator keys. Caps lock light! :) Comfortable and easy to reach keys whether propped up or laying flat.

I had an older model that finally died. This one is so much better and more responsive. Could not be happier!

This is the best super low price keyboard mouse combo that I have seen. I was looking for a combo like this for a long time.

The keyboard is quiet and responsive, easy to type on. The mouse is also very responsive. Both are wireless, so that's great too.

Previously been buying Logitech's Target branded wireless unit. Finally decided to upgrade and the Logitech MK540 fits the bill. The keyboard has a quality feel and the keys make data entry easier. The mouse also easy to use. It paid to upgrade.

-plug and play -light weight -decent battery life

Very good ergonomics. Excellent battery life. Key strokes are responsive and the keys are slightly cupped in middle for a better feel at the finger tips. Mouse is precise. I've used it for gaming as well. Not the best at gaming since it's a wireless mouse but has a higher dpi (3200) compared to most and gets the job done for casual gaming. I've have the same keyboard for about 3 years now and have had to replace the mouse once in the last 3 years. I've always loved how the mouse feels in my hand.

Price was great, plug and play in Vista, comes with batteries, and the single dongle for both devices.


What more can you say then the keys are easy to press, its black, usb, and its from a fantastic manufacturer


It is easy to type faster than a lot of keyboards. It has tactile feedback without being too much. It can be used with up to three different devices, although I haven't tested that. The mouse has a nice feature that you can turn on and off the ratcheting of the scroll wheel.

Great feel to the keyboard. Glad it isn't split in the middle like most ergonomic types


My reservations were twofold. The price was a bit expensive, and I was unsure about it's ability to enter a computer's BIOS. I have been using a variety of keyboards since the mid 80's, and this one is the easiest to use with relatively quiet keys, unlike other mechanical keyboards, and I can get into the BIOS on my three desktops with ease. And once using it, I haven't thought about the price at all.

Mouse is comfortable and has no 'delay'. Keyboard is also comfortable and responsive. Doesn't feel 'cheap'. I bought 2 and swapped them out with other 'wired' setup.

Testing the new keyboard it is very nice I like this keyboard. It is smooth the keys work well and I have no issues so far. I like the media buttons and I can pair it to my phones which is cool but so far I have not used. Overall I am impressed and this keyboard is very nice. I had a Microsoft media keyboard until I spilled coffee on it and had to buy a new one. This keyboard is an improvement and I like it.


both devices use the same USB adapter or bluetooth

No software required to operate the lighting. MX red switches and PBT key caps feel great very light actuation pressure Solid construction and comfortable to use. Standard Cherry MX key-caps so you can swap the key caps if you so desire
