In principle, a normal mouse, if frequent and precise use of the scroll wheel is not required, otherwise there are no complaints.
Some pros:
Price, acceptable in the hand, dpi switch. Normal build quality
Different cons:
The scroll wheel breaks quickly, on all the a4s that I had (3 pieces), I thought that I was just unlucky, but I bought this mouse, and broke off for the fourth time. When scrolling, it twitches back and forth, sometimes generally refusing to zoom in or out.See full review
