I just received mine and i can proudly say I'm the first owner in all of the US considering how they quickly pulled it off Amazon.
I got the xsoft version and it is much faster and smoother than Hayate and Hayabusa. The speed is the same for both vertical and horizontal movements.
Out of the box right now it feels as fast as a shiden but not as slippery, so the control is way better than shiden.
I have every single artisan pad and this is the best one so far, they need to make a Large version so all of my friends can buy it.
Hope it doesn't stop working after 3 months like the garbage Shiden does, but i doubt that considering Raiden is cloth top, but we'll see.
EDIT: Pics with horrendous quality
