Logitech MK540 Advanced Wireless Keyboard and Mouse Combo for Windows, 2.4 GHz Unifying USB-Receiver

Top notch quality of keyboard and mouse

Keys are smooth and responsive with practical shortcut keys and good built quality.Mouse feels comfortable to use and fits hand completely.Initially got a faulty keyboard with delay on keyboard response but was replaced in time.

Smooth keyboard, no clicking sounds of keyboard. I am not sure if it is overpriced or not. Comparing with my previous Dell Wireless Keyboard and Mice set, this is totally a high quality upgrade for me. So far the mouse battery is still working fine after my purchase. For the keyboard I am using rechargeable elenloop batteries, so cannot comment on the batteries supplied with keyboard set. I will highly recommend anyone purchasing wireless mice and keyboard set to switch to rechargeable batteries, if you use this as your daily driver. I feel comfortable and easy to work with this set. Sometimes the keyboard input feels lagging, not sure if it is due to os overload or something, but it is very rare and doesn't cause too much issues. It resolved automatically in a couple of minutes. Overall I felt good with this purchase. No regrets.

I was using Logitech MK215 Wireless Keyboard and Mouse Combo for a long time, they were getting harder to press, specially enter key need to use bit of a force to press it..my fingers would start to hurt after prolonged use ( am a developer ).buying this keyboard was a good decision, the keys are really smooth and is comfortable to use for prolonged use.this keyboard is quite long compared to Logitech MK215, but if you are coming from mk215, then trust me your muscle memory is safe, because the letter keys seems like they have same alignment( size, width or whatever you want to call it), so you wont find yourself pressing wrong keys, except for num pads and arrow keys, they are quite far.if you are coming from mk215 like me then, you'll find this more comfortable.

The media could not be loaded.  Keyboard - 1/5 for looks. Everything else is disappointing. Detailed review below.Mouse - 5/5 - Sits very well inside the palm. Rubber sides are also very comfortable. Very pleased.Do not purchase this keyboard if you are used to having a clear tactile feedback from your keyboard. This keyboard trades off tactile feedback for silent typing. It also trades off ergonomics (fingers easily hitting multiple keys often due to rounded edges) for looks.Usage pattern - I type looking at the keyboard for about 60% if the time. I still prefer to have a distinct tactile feedback on hitting the keys. I type mails and code.Tactile - The response is neither like laptop keys nor like mechanical-like keys which I use at work. Laptop keys have a clear "give-in point" where the rubber membrane falls in. Mechanical/mechanical-like keys hit a solid bottom with audible sound. The keys on this keyboard don't hit any bottom which is to avoid to avoid noise, but also the rubber membrane doesn't have a clear "give-in point" like laptop keys do. This makes the typing experience very unpleasant.Keys - Rounded edges with little space between the keys is the perfect recipe for mistyping. On an average my fingers would touch the adjacent keys (with or without causing a key stroke) pretty more often as compared to a typical mechanical-like keyboard that would have sharp key edges and ample space between keys. The very sensation of an adjacent key on the finger is an annoying one. Combine this with tactile issues, ₹4000 spent on this feels wasted.I will soon be switching to a different keyboard.

The mouse battery did not last more than 11 months instead opf the advertised 18. I wonder if the keyboard batteries last 36 months. I also miss the row of keys above the function keys with buttons for e-mail, media volume etc., that I had on my previous logitec model (unfortunately,I don't remember the model number Otherwise I am satisfied with this.

This is a very comfortable to use keyboard, keys are very smooth, and has right balance of travel distance on press and yet silent. The undulating curve on each very is also good design. The prints are clear and hope it will long. The short cut keys are very useful. The keyboard and mouse are very easy to set up and just works seamlessly once the dongle is plugged to the usb port of laptop. Includes battery from Duracell is very customer friendly gesture and eases the setup right out of the box.If I have to be picky about two drawbacks1. The palmrest could be little bigger and soft fabric for better feel2. Mouse could have some side buttonsThe same keyboard is sold in Amazon US at similar price point with the above two features included.

The mouse is good with omni-ergonomic design and grip n all is great although keyboard should be better in my opinion the keys are too soft I had mistyping issues for about a week but it's fine now anyways overall product is a great.

Really top quality

The keyboard and mouse worked out of the box. The keys feel very good and make a minimal noise.

o.k.

Nice keyboard and mouse.Be warned - The tiny USB dongle is discretely hidden in a piece of cardboard inside the packaging. I had to fish it out of my wheelie bin about an hour before it would have been lost forever to the garbage truck. Logi are tempting fate packaging things like that and selling it to careless distracted folks like me.

There was everything to like about this product, in fact there was not one thing to dislike about this purchase and transaction.
