Following the advice of some friends, I opted for a slightly rough flexible model to improve my accuracy.
And actually I am very satisfied at this level as well with my Logitech - G500 with my Cyborg - RAT 5.
In both cases, the slide is in accordance with my expectations, i.e. moderate, regular and controllable.
I hesitated between a size M and size L, wondering if it would not be too great. But actually no, the size L is really what I needed.
This offers great freedom of movement and, as I have a glass desk, I can put my arms on the mat without the unpleasant sensation of cold in the wrist.
Otherwise, I have no complaints about this carpet. The quality of finish is quite correct and adheres well to the base office.
I recommend.
