ugh, i hate those scroll wheels. i can imagine the "casual user" could love them, but for me they are just loud and noisy, heavy, wobbly, unpleasant notches, unpleasant M3..
i mean, i never used the free-scroll function, and never used the rocking buttons (left and right from the wheel).
the wheels i like most are the simple mechanical encoders, unfortunately most companies cheap out on them and they still end up feeling mediocre.
anyway, i'm back at using the G400 again. i can't say i even like the shape that much, but i'm just so used to it..!
i still don't like it for gaming all that much, but i'm gaming less and less these days anyway. the shape cramps my thumb if i have to lift the mouse up a lot
