As suspected, got the G603 for my birthday last week 
Great mouse, similar weight to my 500s that it is replacing, so don't see what the fuss is about regarding weight. Clicking noise is okay (which was another issue people raised), it's not that bad, then again I usually play games (i.e. have the volume up/headphones on) when I excessively click it enough to notice the noise.
It's great being able to switch devices with the press of a button, both bluetooth and wireless work flawlessly.
