Picks up dust and sweat

This carpet is very soft, very thin and light. My mouse (Razer 3x) glide very well on it. Adaptable to many surfaces and as stated in its description, it will slip between the screen and the keyboard of my laptop.
But the synthetic coating is also to attract dust, cigarette ashes, etc., all small particulates. This is annoying in the long run because it also simprègne sweating and friction from the palm of your hand: the long (two months) it swells, warps, and a white trace (like the armpits of a black cloth) emerges on the carpet.
You go to the washing machine or wash with cold water; nothing works. In a few months, you have become a dust cloth rag good to throw.
This is what I had to do and replace two belts (three) which were my gamer carpet. You play several hours a day, go your way, it's not what you need.
It is good to be slipping into a laptop between keyboard and screen to little use in everyday life.
I stayed on the same mark with the purchase of two Razer Goliathus Size S (this size is already very high to me): Razer Goliathus Fragged Omega Speed ​​Mouse Pads Gamer Size S. I will say a little more these mats when I have tested them in several months. For now I have the impression that the matter of the carpet is not the same. See with time if I find the same disadvantages.
So carpets to avoid: money thrown out the window in the wind and dust.
