Pros: shape - perfect for my little girly hands (one of the few mice I don't have to hold at an angle in order to comfortably reach all the mouse buttons), love the 'hump' being toward the back weight - nice and light, I used to like heavier mice with high DPI and use the weight for control but it can be fatiguing when lifting off a lot, like with FPS games so this mouse has allowed me to drop my sens and still feel in control and like I can rotate quickly no extra blingy LED BS (I'd like to see a cost reduction for this tho)
Cons: side buttons: travel distance is a little deep, not a nice solid click scroll wheel: scrolling is fairly terrible, requires a good bit of pressure to make sure it registers the scroll movement, clicking it is fine
