A defect that ruins everything

Keyboard return back after 2 weeks of use.
The only problem with this keyboard is that when one clicks a button, it still sinks a little which is very disagreeable for fps games (CSGO in my case), we feel that the key is not going up at bottom so to speak. In addition, sometimes the function of a key block can remain without being continues to support it.
By cons in terms of game managements moba style, or other games that do not require precise movements with the keyboard, the keyboard may be suitable.
As for the rest of the design, choice of materials, nothing to say. The hand rest is very nice, comfortable typing too. I greatly appreciate the button to pause the computer.
It is with regret that I return the gamer keyboard because it is the only one, to my knowledge, who owns the flat keys like laptop.
