At least half of the time it just won't type into the computer what you have typed. You can't even delete something. It will have to go back. If it would consistently work, it would be a great product.

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.

Works well with may laptop.Many options can be modiified for individual use. Great Buy Would like to see a keyboard light for the NumLlock Key..

Features

Not only do I have Carpel Tunnel, I also suffer from Lymphedema. As a result, my hands swell and experience needle sting like pain when using a regular keyboard. Therefore, I need a keyboard that is ergo designed yet compact. Logitech is my Godsend. It not only meets "the bill", it exceeds it.

Accurate Tracking; Comfortable Design; Fast Response; Glides Smoothly; Great Features; Works On Any Surface

I bought this for work and it hasn't let me down. It has been used 5 days a week/8-10 hours a day and I haven't had any problems. Great set - great price.

A powerful keyboard and mouse set that meets my computing needs. Great price, very easy to use, and is very dependable. I really like it.

Very simple setup. Plug dingle into spare USB socket, pull out battery protectors and use. Not a lot to add. Does the required job with no fuss. Both keyboard and mouse use the same dongle so only one USB slot is tied up.

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
