Competitive gamer reviews: Logitech G502 review, 3366 sensor

Conclusion/summary:

Returning the mouse.
Too heavy, poor button placement, too narrow in the back, scroll wheel too far back, middle button hard to click causing accidental scrolls, and ultimately the sensor still doesn't match the MLT04.

Pros:
Good build quality, good grip, shape is decent, sensor is decent, features are nice, cable is flexible enough that it doesn't hinder mouse movement and stiff enough that it's not flopping around.
