THis shape looks pretty much perfect for me, one detail that old logitech mouses had, which this one do it right (for me) , is that the tail is not lifted, the other point is the grip seems rubberized and textured. Really would like to try it, my g603 is kida a let down (for me), don't feel really precise while clicking.

Looks a bit like my trusty Logitech G700. I've been looking for a successor for years. Just curious - how does the button mapping software work? Do I have to run the iCue software in the background permanently or do your custom buttons/keys it reside in the mouse firmware in some way? That's one of the nice things about the G700. I don't have to run the Logitech Gaming Software at startup or ever again for that matter. Just configure the buttons once and you're done.

I am not sure which of those 2 mouses reviewed today has more inaccessible thumb buttons. Shape of both is quite OK, but those buttons and geometry around them would get on my nerves pretty quickly. Those "Skates" look rather large... large contact area with mouse pad is usually not desirable. And I wonder why so few manufacturers use metallic "Skates".

iCUE has got to be the glitchiest software i ever used. And that's saying something coz Electronic Arts usually holds that title

If its like the dark core I have, it can retain hardware profiles saved to the Mouse itself.
