Getting perfect hand, much better suited to the FPS G600.
Molette more accurate than G600.
A button under the ring in less against shame.
Drivers at the top, really, very intuitive: you can adjust the height of the stall, they update automatically, you can calibrate the mouse in his carpet ...
The glide is perfect, it is beautiful and elegant, the braided cable which is essential. Long. Nice texture, a bit "dry" and holds very well the blow.
You get used may be slower to navigate the pad under the thumb relative to the G600 but that's long as it's not a problem.
A good product as usual, because a good brand that has proven itself and will strictly NEVER disappointed me or released after a few months (I am a brute with mice) like any other at a time or another ...
I highly recommend this product.
