Purchased this wireless keyboard as I'd read that it worked with Samsung Smart LED TV's. Received the keyboard, scanned through the directions and plugged the Logitech Unifying Receiver into the USB port of my Samsung UN40ES6500 40" TV.

For only $40, Logitech's K400 combines a keyboard and touchpad in a lightweight, wireless package that seems ideal for the living room.

Despite its flimsy build, the K400 is a decent budget HTPC controller, with its built-in touch pad a surprising inclusion for the price.

Compact; lightweight; Built-in touch pad; Robust selection of function keys; Easy setup

Cheap plastic build; Mushy keys; No backlighting

this item is ideal for every day use

Really great so far. Wish it was back lit and that the arrow keys were under the track pad. Also I got sent the K400r (lucky me!) which has great gesture recognition on the track pad. Very small and light.

We bought a cheaper keyboard with a separate mouse. Too many remotes and clutter meant that the mouse dropped and broke. However, this Logitech keyboard is ideal because it incorporates a track pad as well as mouse buttons. So easy to set up and use, instructions are almost not needed.

First, I purchased this to watch TV through a computer. I cannot speak for any other use. Just a note, the keyboard that came in was white, not black. I know not why, though it's a non issue in regards to function.

Very comfortable and space saving design. Its simple plug and play. The touch pad feels Ok too. There are no caps lock lighted keys though! oh well..........

This keyboard is cheap, stylish and a great tool to use with a HTPC. The range is great and though I can't personally speak about it's battery life yet, everyone else seems to have good experiences. There is ONE thing missing though.

Style; Size

Work with your computer the way you're used to, even when your computer is connected to a big LCD TV screen - it reads on the box. Well, my desktop PC works with a 27″ LCD display, so sometimes I want to relax, sitting carelessly with a keyboard on my lap. But what about mouse?
