  • newegg Type Right and in Comfort The keyboard (K520) features a full-size layout and a palm rest to offer the room you need to type comfortably. Whisper-quiet, concave keys position your fingers properly, and their softly rounded edges invite your fingertips to glide from key to key, hour after hour. You can also extend the folding legs to increase the keyboard tilt to 8 degrees to address your personal ergonomic needs.
  • newegg Hand-friendly Laser Mouse (M310) The contoured sides and soft rubber grips keep your either hand comfortable, supported, and in control. You’ll enjoy smooth, precise tracking on virtually any surface thanks to the laser sensor. (The laser sensor does not work on glass or mirrors.)
  • newegg Batteries without Hassle A battery life of up to three years for the keyboard and one year for the mouse practically eliminates the need to replace batteries. (Battery life may vary based on user and computing conditions.)
  • newegg Logitech Unifying Receiver & Advanced 2.4 GHz Wireless Advanced 2.4GHz wireless technology delivers reliable wireless connection with virtually no delays, interference or dropouts even in the busiest wireless environments. The tiny wireless unifying receiver stays in the USB port and connects both the keyboard and mouse. There’s no need to unplug it when you move around.
  • newegg Instant Media Access One-touch media controls on your keyboard let you mute your computer or skip to the next song instantly—without using your mouse.
  • newegg Easy keyboard storage You can store your keyboard standing up to free up space on your desk.

5 out of 5 eggsGood Sturdy Product

Pros: Good price and sturdy build...Easy to install and long battery life...This product has stood up to over a year of abuse from my 5 year old daughter and is still going strong....very handy for my living room setup

Cons: i have no complaint with this product.

Other Thoughts: This was my first wireless keyboard and mouse i have always been a wired guy so i was skeptical that is could hold up to the abuse...i have been very please with this product and how well it has held up to the abuse we give it in the living room.

5 out of 5 eggs

Pros: Reasonable price and low battery consumption

Cons: None

Other Thoughts: After 18 months of usage approximately, I just changed the mouse battery because it died and they keyboard is still running with the same battery (two thumbs up for that). Also, it is very ergonomic. I love the feel to the keyboard keys and has good range (I've used it across the room without any problems)

1 out of 5 eggsDon't ignore all of the 1 egg reviews!

Pros: Looks good, has media keys. Good distance on the mouse, when it works (see cons).

Cons: Spotty at best, often a 10 second delay between typing and letters showing up on the screen. Mouse regularly stops working; power cycle usually fixes it for another few minutes.

Also, minor complaints compared to the "it doesn't work at all" bullet point, but: keys are shallow and soft, tactile feedback is pretty bad. Mouse is a little small for my hands, and has no side buttons.

Other Thoughts: I paged through the reviews here before I purchased, and paused a bit at all of the 1 egg reviews regarding reception and lag - then I told myself that with the overwhelming amount of positive reviews and my past experiences with Logitech, "it'll probably be fine..."

Big mistake. I got two days of pretty solid use out of these before they started having MAJOR lag issues.

Don't ignore all of the bad reviews here, this set is absolute garbage. The Microsoft sets in the same price range are much more reliable.

5 out of 5 eggsFirst wireless keyboard/mouse

Pros: Solid wireless connection. Both mouse and keyboard work well for me.

Cons: Batteries will eventually run out.

Other Thoughts: I was concerned the USB/wireless combo would not work out, but I was wrong. They both work, even in BIOS.

1 out of 5 eggsSevere lag issue

Pros: It's a good price, and I've always had a good experience with Logitech.

Cons: Severe lag issue, especially in games. Unifying receiver is within 1/2 meter, and all fresh batteries. All drivers up to date. No other transmission sources within 3m. Characters typed are hit and miss... more time based than per character. Keyboard will become non-responsive for several seconds and then work for several seconds. Spews queued characters. Mouse is similar... visibly choppy motion.

Other Thoughts: Googled the problem, and have found reports of this issue dating back to 2006. Yikes! Logitech occasionally chimes in with level-0 tech support (lip service), but no solutions ever.
Try a different model, or a different brand.

1 out of 5 eggsReplacement Bad Also

Pros: The mouse is great. I like the design of the keyboard, but I'm not a touch-typist or even a good keyboarder.

Cons: This is my second keyboard, and it started out good, but now it lags. Logitech just sent me the replacement with minimal problems or questions. That now makes me think they know there is an issue.
I never had a problem like this with Microsoft...I just couldn't stand their keyboard design. Still can't.

Other Thoughts: I wish there were a firmware update that would correct this issue.

My rating has gone down to one egg now.

2 out of 5 eggsFail design

Pros: Inexpensive - works ok for the most part

Cons: No numlock indicator.

Logitech thinks I should load an application to enable an onscreen indicator that the numlock is on.

That's a paddlin'!

Other Thoughts: Removing this model from our purchase list.

I like Logitech historically, but I fear they are trying to play to the bottom of the purchasing curve.

We don't live there, so I guess I need to find a more professional model.
