Logitech K800 Illuminated Wireless Laptop Keyboard Compatible with Desktop, Laptop, Mac  (Black)

I've been using this keyboard since 6 months now, i've used wireless keyboards from Microsoft in the past.
The Good:
- Very responsive keys with sufficient tactile response
- It's a delight to type on this keyboard
- Backlight feature is great
- Good range
- The included charging cable (standard micro USB), is long and includeds a winding strap. Can be even used to charge mobiles :-)
- The reviever is a unified receiver which means you can use the same one for multiple Logitech devices.

I got this keyboard around 9 months back and was very excited and happy with it. Just a couple of days back all of a sudden 5-6 keys stopped working. The non working keys keep on typing dots on notepad or wherever clicked on. Totally pissed off. Moral of the story is, Ultimately you dont need extra features if the basic needs are not met!!! Logitech come on... make some good products rather than this kind of chinese items!!! :P

Pros
* Extremely easy to use
* almost silent key press
* backlit keys, can work in dark
Cons
* poor battery life if you keep backlit on permanently, otherwise will work for days.
* hard to press function keys with additional function support.
