Logitech - K400 Wireless Keyboard - White

I purchased a Samsung Ultra HD TV from Best Buy. I found out that when using it to access the internet or other areas that needed info added, the on screen input method was cumbersome. I decided to purchase a wireless keyboard to make the process a little easier. I looked at the Samsung model which seemed a little pricey for occasional use. I then looked at the Logitech K400 which was on sale and decided to take a chance, and I have been quite pleased with it. It does not have some of the dedicated function keys that the Samsung has, but I do not find this to be a problem. And the touch pad works great also. All in all I find it to be perfect for use with my smart TV. I would highly recommend it to anybody looking to purchase a wireless keyboard.

The keyboard is just the right size for me. I'm a 2 finger typer so it's easier for me to get used to the reduced size than it would be for someone trained in typing. The mouse pad works good also. There was no documentation on how to use the special buttons at the top so reduced the rating to 4 stars.

It has changed my life! I can't stop using it. I carry it with me everywhere and go and share it with friends and family members. I have finally found my true love!

The keyboard is usable, small and has a built-in mouse pad. The weak part of this KB seems to be twofold: if you don't have direct line-of-sight or nearness between the KB and blu-tooth fob, the mouse pad is not very accurate and sometimes non-functional.

The product picture shows a K400, however, when opened the box, it was actually a K400R- working ok on PC but not on my Samsung TV. and Nano Transceiver dongle is difficult to plug into USB port on TV

This is a compact Keyboard for easy use on all Samsung bluetooth compatible equipments

I purchased this for use in my basement recording/rehearsing studio for remote input to a DAW PC. Wireless range seems adequate in my 20'x12' space, although I have not tried it from every corner of the room. I am still using the original batteries, so I am happy with the battery life so far. Keyboard is small, but usable. My only complaint is the right Shift key, which is easy to confuse with other adjacent keys. Touchpad is responsive and very usable. The portability and convenience of the keyboard/touchpad combo more than compensates for the familiar and comfortable functionality of a conventional mouse and full-size keyboard.

The Logitech K400 wireless keyboard is very handy and easy to use, reliable so far and only $20 at Best Buy in Dec '14. Arrived quickly, insert batteries, follow instructions, and it works! Remembers password so no need to input it again whenever you start it up again. Have used Rocketfish and lesser-name keyboards in past that didn't work or disconnected constantly; don't have those problems here. Only odd thing here is you have to hit Function key and End (or Home or Page) if you want to go there; if you want to select a bunch of emails to delete, for example, you hold down 3 keys (shift-fn-end) whereas normal keyboard only needs shift-end. Also remember to turn if OFF when you walk away for long time or batteries won't last. But keyboard is light, mobile, slim and working great with my Dell laptops.
