I have bought this mouse+keyboard combo a month ago.The keyboard does not always respond,I type and either nothing appears or after some delay part of what I typed comes up. Sometimes the only way get results is to really bash the keys.

Purchased this wireless combo as a replacement for my supervisor. Only after a couple months use, my supervisor began experiencing various keys sticking. I've already thrown away the original shipping box, but hopefully, I can obtain a replacement or repair under warranty.

This is the 3rd MK520 keyboard and mouse that I have purchased in the last few years. All 3 are still working fine; 2 with desktop PC's and 1 with a laptop. They all worked fine right out of the box.

I do a lot of ancestrial research and on the computer hours at a time. Although the hand rest on the keyboard is a little lacking it works out find.

Comfortable Design; Easy To Set Up; Fast Response; Highly Compatible; Quiet

HEAL REST FOR HANDS SHORT

Works perfectly. Was able to download the software compatible with Vista operating system. The price of the hardware was quite reasonable.

The Logich MK520 Wireless keyboard and mouse serve well as desktop peripherals. The mouse has a laser guide, so it's fairly accurate. It'll work over most surfaces (except glass, you'll need Logitech's Dark Field Technology for that).

Pretty excellent product overall. Odd to have a Keyboard with a function key but it works well in Linux Mint with most of the functions working out-of-the-box, the rest easily configurable within Keyboard Shortcut settings.

I didnt realise how many mediocre keyboards and mice I had put up with over the years until I purchased this combo. Comfortable keyboard which is forgiving of my ham fisted typing and a mouse which is super fast and precise. Probably one of the cheapest productivity improvements going!

Best KB/mouse combo I ever bought, and I am managing a lot of those (about 50 kits). All the other brands or cheaper Logitech kits don't last half as long as the MK520 combo.

Good, I will recommend this to my friends.

Good Keyboard and mouse; Silent Operation

Doesn't have a Indication for CAPS ON/OFF; NUM Lock
