Oh that's cool, I've never seen that palm plate design before.
The mouse has three adjustable sensitivity modes, three "gameplay modes" (so I think theoretically you could have 9 sensitivity modes with 3 button configurations), thumb wheel, scroll wheel, a "sniper" button (the red button on the left near your thumb) that reduces your sensitivity to a very small amount - I never use it, as it's kind of awkward to be holding left click and my thumb and press fire all at the same time - so I just stick to the sensitivity mode switch.
It's also got two thumb buttons and adjustable weighting, along with roughly 50% of the mouse (pinky rest, thumb rest, palm rest) being repositionable/interchangeable.
I like it a lot, it's a bit over the top but not as much so as their other products (just look at their Scorpion keyboard), and it's a good quality mouse that feels very solid (the palm rest is a bit wobbly when it's fully extended but it's no big deal). I would recommend it.
