Logitech G602, personal opinions?

Hey guys, I'm looking at getting the Logitech G602 wireless mouse. It looks like they managed to solve a few of the bug bears that people have had with wireless mice in regards to gaming, which is promising.

I live in Aus so the thing is gonna cost me the better part of $100 and I'd like to know if the mouse actually lives up to Logitech's claims before I seriously consider dropping money on it. So I pose a few questions to those who have it or have experienced using it.

Do you think it's worth the price tag?

Does it stack up to logitech's claims in terms of performance(battery life, sensor precision, etc.)?

Is it comfortable to use?  

Your overall score of the G602 out of 10?
