Got the mice a few hours ago, shape was fine really. Played a few games of csgo and it feels better compared to other mice I have (g400, g402, deathadder 2013). I hold it sort of like theGMT, except my thumb is lower down (covering 90% of the forward side button) and my hand is ~20 cm from wrist to top of middle finger. The mouse rests on the top right side of my palm only taking up ~5% of the palm. Never had a problem with the new cables as I can just put it behind my monitor and it will act like a bungee of sorts.
The mouse wheel click is also a lot better (lighter) compared to the g402. I can make it malfunction when trying, but inside the game with normal play it didn't happen (~43cm/360). The calculated speed is ~2.1 m/s according to
which is fine and below the g302 malfunction, which is around ~2.7 m/s
The mouse buttons do feel nice. Obviously I don't have other small mice to compare it too, but ill see how the fk2 is after a few months or maybe the 3310 Aurora.
