Out of the box and plugged in the mouse was very erratic so I downloaded the Logitech Unifying software and got an immediate improvement. The more I use this keyboard and mouse the more I like it.

Had this for over two years ... just replaced the mouse battery. Never had any problems, I would recommend this to anyone after the wireless experience

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..

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.

"be patient don't break anything" is sentence that I have had say to myself too many time this past month. The mouse works like a charm. But the latency in the keyboard is enough to drive any man insane. I wouldn't recommend this keyboard to my enemy.

I bought this product a couple of days ago and thinks it's great as I have children it is so much easier for me to use an browse the net and send emails ext I also connect my laptop to the tv and lay in bed an use the key board would recommend to anyon to buy it

I have got around 30 of these Logitech MK520 desktop bundles in operation and all the users love them, with no failures or wear problems to date. Very tactile and aesthetically pleasing with excellent battery life.

Great product, excellent price, and I received the order very quickly. I love this keyboard and mouse from Logitech. Slim, comfortable design, much better than OEM that came with my desktop. I would definitely buy this again.
