I recently hung my monitors on a dual monitor arm and hid the cables so the only wiring on my desk was a mouse and a keyboard. This was unacceptable. A few of my co-workers have this same Logitech keyboard and mouse so I did some searching around and found Best Buy had it for less than I could order it online when you factored in the shipping charges. I ran over on my lunch break and picked this up. The keyboard works great, the keys are quieter than the old Dell USB keyboard I replaced. The mouse feels comfortable also but I do wish it had the forward and backward thumb buttons which are handy when using the internet. One co-worker says he has left his powered on for over a year and the batteries are still the originals. I turn mine to off every day when I leave work and I hope for as long of battery life. The manufacturer says 3 years which is a long time. I will be buying another one of these sets for my home PC as well.

This keyboard and mouse was easy as plug and go. Worked flawlessly. Very happy with purchase and price.

Over the past year we have been replacing the standard wired mouse and keyboard with the MK520 Wireless Keyboard & Mouse combo on many of our computers at all of our locations and have been very satisfied! So much so that I purchased the combo for my personal use as well and love it!! Again performs very well!!

Effective for my use with 2 laptops instead of using the integrated keyboards and pouchpads.

No need to deal with wires.easy to type on. Under desk on pull out shelf easy to use.Great buy!
