I had to get used to it a little because the ring finger constantly pressed the shift. The force of pressing the shift can also be adjusted for yourself by placing a spring under it, there is a window on the side, but there is no spring in it. In principle, as a finger gets used to it and does not interfere later. By default, the mouse is a little heavy for me, but I play by moving the mouse with my fingers, it feels a bit heavy. I took off 1 load, without it, by weight, like a radio mouse with one battery, now with my fingers just right. But without two weighting agents, it feels a little heavier than a regular mouse with a wheel. In general, a suitable device for MMOs and even shooters can be completely after adjusting the weight.
