Meant to reply to this the other day!
I love the wheel, its fantastic and im surprised how well it works with a PS3 considering its designed for an Xbox.
Build quality is amazing, so is the feedback in terms of judging how much grip you have and when you are under steering or over steering.
I cant use it wirelessly with the PS3 which is a bit of a bugger as I have to daisy chain three USB cables to reach my PS3 from the sofa
I also cant use the clutch or 7 speed manual gear stick but its not the end of the world. They work really well in Forza 4/Horizon.
Only major problem I have with it at the moment is it doesn't seem to want to remember the ABS vibration setting so I have to turn it back on everyday. It also seems that after playing for a while GT6 stops registering 100% throttle. For a while was lapping brands only being able to use 90%. I couldn't figure out why I was always about a second slower than my ghost.
With the above in mind its still running the firmware from the factory so I wouldn't be surprised if an update fixed those.
