Dell Wireless Keyboard and Wireless Mouse works great!

I like the convenience of having a wireless keyboard and mouse because I do not feel the need to hassle with wires while working on my projects. It is less restrictive and the battery life is good for over a year or longer. I have not had to change the batteries yet. There have not been any missed keyboard strokes or mouse clicks. I used other more expensive brands and this wireless keyboard, and wireless mouse works simply fine.

Perfect for new AV room

I use the wireless keyboard and mouse in the new AV room. It has good range and will work around objects well. I like how the audio volume buttons are easily accessable . Quality is consistant as I purchased one a few months ago. I knew it would "work out of the box" and wouldn't have any issues with it. My time is limited so this feature is important to me. I have little time for things that don't work.....but this product does.

Wireless keyboard & mouse

Nice upgrade from the wired keyboard and mouse included with the desktop purchase. I wish Dell would consider offering a backlite keyboard similar to the Logictech t800 which is no longer available. It would be a nice upgrade and I believe others would also order when purchasing a new system
