It doesn't, I bought mine from Amazon just 3 weeks ago and it still has the clicking sound everyone goes on about.
Then you are in bad luck. I have my G25 replaced by Logitech (shifter was broken of the first G25). There were no G25's in stock, so I had to wait a few weeksfor a brand new model to arrive at Logitech before logitech was able to replace my broken G25.It doesn't, I bought mine from Amazon just 3 weeks ago and it still has the clicking sound everyone goes on about.
And, indeed, the shifter doesn't make that clicking sound anymore. Maybe you bought an older model (stock).
