The finish is successful, roulette (which I can not say the matter ... but not of the same metal that G700 anyway) is detachable like most logitech for scroller is TOP. Small problem, however, when the latter is disengaged, the clicks of the knob becomes difficult to achieve without scroller (the G700 does not have this problem).
If the sensor is great, a huge precision! Good by cons not climb above 3000dpi failing to shop around your screen by a micro wrist movement ...
