The purchase was not entirely successful, there were minor problems in use.
This is my first wireless mouse and the 2nd one I try for the left hand, after the ZA11. Definitely not the option that I will dwell on, but if it suits you personally, it's just a gun, not a mouse.
Pros
Customization, interchangeable mics, the ability to put a blank on unnecessary side buttons. Comes with mics and plugs. Wireless. The weight of the mouse feels great, maybe a minus for someone, but nonetheless. And most importantly, the ability to play with the left hand.
As a consequence, the next + is its sane price.
Cons
Everything here is strictly subjective and it will be clear later why.
I play with the mouse in my left hand. The mouse does not provide anything to support the left side of the hand, due to which the hand gets tired in 10-15 minutes.
With the left grip, for lack of another place, the ring finger can fall under the RMB.
Not suitable for a palm grip (my hand is 20x8), after listening to Shelest, who recommended it just for him, I decided to try it myself, but no, it’s still better than the g403 in the hand that doesn’t lie well (but, alas, it’s not under the left).
PS.
Another important point, there are slots on the side for a better grip, but on the left the fingers go further than them and strongly, and if they sweat, the mouse easily slips out, which makes it necessary to strengthen the grip, again overloading the brush.
