Pros: Sensor accuracy , reactivity of clics switchs, the shape very litle and light
Cons: the click are a bit hard and feels a little fragile check in time, coated cable too big and heavy
The G303 is right now my favorite mouse ever i have tested Deathader 2013, Mamba v2, G9x and Logitech rx250 (basic office mouse) and the G303 is the best of them in term of tracking feel, precision and shape (equality with rx250) Moving from the legendary G9X to G303 is like night and day I live a quake player and I feel I am much more accurate and faster with this mouse is very light. I love little and light mice because it's better for fast games Imo G303 is the new king of the gaming mouse I became immeditaly quake live god in instagib with good menu settings and custom course cvar of course. Current manufacturers should take inspiration from the shape and weight of the mouse to their future production, since the G303 comes close to perfection. I feel a real downgrade in terms of precision and ergonomics with G9X that says it all its flaws: his bad skates customize put 4 small like those of intellimouse 1.1 and can be angled his side although they become insensitive when used. the biggest negative is the price 68 euros for a mouse a improved version of 302 i think the g302 is enough for precision and that the new sensor not justify the price difference.
