Had this Keyboard for about a month now I guess, absolutely awesome!, love it. The only one on the market of its kind and Logitech have exceeded expectations. If you want a great wireless gaming keyboard with mechanical keys, & not having back lights isnt a issue then this is for you. Great for FPS game's as well as others. Have had no latency issues what so ever not matter what game I'm playing!.For the price it's a absolute bargin!
