Now a few hours with mouse in hand. I could have played some including League of Legends and CSS and I can guarantee that this mouse is frankly super effective. I feel much more accurate and my game I found better, more fluid. As for the "physical" side of the mouse, I have nothing to say, she is super sweet, so it may seem odd, but there is no feeling of sweat, it does not slip! It is perfect for my style of play! Are also more on this mouse, the fact of changing the color of the logo, you have free choice. You can leave the steady light or not, or turn it off (for the night it does not turn off when you shut down your pc). A small software is supplied by downloading the drivers on the Internet. The number of click and the distance traveled is you provide. It is a small gadget, it's funny. You also have the configuration of maccros keys (MMORPG), you have a choice of backup. However I put 4 stars for the state of the sending of the parcel and striped packaging! This disappointed me to receive a striped box because being crazy computer I like to keep my boxes and I did not even want to highlight it.
In short, to tell you that this mouse is its perfect price! Optics is what he has to better reaction! Oh, and the son are woven, so it is still an advantage! Go for it!
PS: For 4000 DPI I do not use them, I stagnated at 2000 DPI.
