If you put your palm on the mouse, then this is the first mouse in 20 years with which neither fingers nor the base of the palm hang down. This is where ergonomics ends . and it started so well. The G-shift button needs to be made wider, now the ring finger on it feels like a person standing on a 15 cm ledge at a height of a 30-story building. The wheel is TOO rearward and too far to the right. while being close to the middle and distal (far) joints of the index finger. or exactly opposite the distal joint of the middle finger. The panel of additional buttons is convenient in width but in length, no matter how you lay your hand, it is convenient to use only two rows (either front or rear) . or crawl back and forth on the mouse. Mouse skew from left to right causes the main buttons to be pressed either A. not from top to bottom, but diagonally, slidingly, tangentially to the surface of the button and the table; b. The palm has to be raised from the mouse, giving it a horizontal position before each click. V. fingers in the proximal joint with each press have to be twisted into a completely non-anatomical position. Which definitely will not add any good feeling to the hand or fingers from prolonged use of the mouse. Conclusion: If you are looking for a gaming mouse because you are tired of being the "pianist" in the game, then this is a dubious choice, with it you will be exactly the same pianist. only not on the keyboard, but on the mouse. To play simply by placing your palm so that all the controls are convenient for you, it will not work within reach, for each press you will constantly have to change your grip by moving your palm back and forth, then left and right. then up down.
