Contact with the mouse is nice.
However, only the use of two main buttons (left and right clicks) is natural.
It is far too small (I do not yet have big hands) and no size adapter on the side, pressing buttons 4 or 5 on the 6 is annoying, even a little traumatic for the hand.
Trying every time to correct the support on one side with a holding another.
I do not recommend it, except for children who play MOBA or MMO.
