After around one and a half of use, the DeathAdder 2013 did not answer for a few more seconds has irregular intervals, but hey it happens and especially coming from Razer I was surprised to see that the product have lasted more than a year.
I decided to order this mouse, and frankly it is sublime ..
When I opened the package I saw nothing special to share anti-slip sides that were orange and mixed very well with the buttons Mouse 4 & 5 white.
Once connected Rival my PC, I downloaded the driver from SteelSeries and I changed my DPI (ICC) for 400 and I removed the function of changing the CPI with the button below the dial (for avoid erreures which can cost chére in-game).
400 ICC, 2.2 sensi on CS: GO, 6/11 on windows and Rivale find myself day after day.
Remember that the mouse is large, wide and a little heavier than can DeathAdder 2013, which does not bother me, on the contrary it is a reason why I chose it. I have the hands of 19.3cm and I use a Palm & Claw grip.
Incredible Mouse, I recommend you this, but be careful because everyone does not like mice a bit more massive than the norm.
