Hi, I am using this product since more then 1 year. Below are few points of my experience. Pros :- 1> The backlight of the keyboard is great. You can increase or decrease its brightness according to your need. 2> It does support windows 8 as it's not mention in specification section. 3> The battery life is great. It also depends on your usage. You can turn off backlight in day and switch it On in night. 4> Hand proximity detection is really great and it increases battery life. It works fine till now after 1 year. 5> Keys are amazing. I was finding little difficulty in start as I am sued to laptop keys but soon got adjusted to it. 6> The rechargeable usb works fine and is of good quality material like the keyboard. 7> The 2.4 Ghz wireless covers a larger area and you can also used it when you connect laptop to television. The wireless keyboard works absolutely fine with greater distance. 8> The unifying receiver sofwatre pairs your device within no time and it's easy. 9> Guys I have LogitechT400Wireless Optical Mouse and have reviewed that too on snapdeal, do check it. Both keyboard and mouse has unifying receiver but you don't have to use both separately. Go to Logitech site mention on product and download SetPoint software and then you can use one receiver for both keyboard and mouse . That's amazing and it works absolutely fine. 10> The keyboard is well built and illuminates properly. You can see each and every key in night. 11> There is ON-OFF switch on keyboard through which you can save battery when not needed. 12> The keyboard when not needed can be kept in vertical positioning thus saving space. Cons -: 1> The only 1 thing which few users need to take notice is the weight. The other wireless keyboard which does not have backlight are too light to handle but incase of this one its little on heavy side.
