Logitech Wireless Touch Keyboard K400 with Built-in...

Most Helpful Review

"These little keyboards are amazing. Perfect for use with game consoles or smartTVs and small enough to stash under your sofa. They last for YEARS on a single set of batteries and they use the unified receivers allowing you to pair many devices to a single USB dongle. Typing on these things does not feel amazing, but it's adequate. Ditto for the touchpad, which has rudimentary support for gestures (eg, two-finger swipes for scrolling).I find it a little easier to type on the k400+ because it has a full-sized shift key. On the k400, half of the shift key has been replaced by an up arrow and it's very easy to hit the arrow instead of the shift while touch typing. The trackpad area seems slightly larger, as well.My main complaint about the devices is that the function keys are not active by default. You have to hold down the FN key to access them and it's very awkward. I use the function keys very regularly but almost never use the alternates (stuff like adjust screen brightness, lock the screen, etc) and it really sucks that there is no way to toggle the FN lock status. And this brings me to the whole reason I bought the k400: the images on the store page clearly show function keys that have no alternate (FN) function. Sadly, the keyboard shown in those images is NOT the one that actually arrived. The one that arrived, of course, has blue alternate keys all the way up and down the keyboard and the blue alternates are the default. So instead of pressing ctrl+F4 to close a browser tab, one must now press ctrl+FN+F4... it's not the end of the world, but it's inconvenient and frustrating.If you're in the market for one of these things, nab the K400+ and skip this more expensive version that doesn't really offer any improvement whatsoever."
