Having had this controller for some time, I feel as though I have the right to give it a fair review. I won't waste your time with techno-babble; all I will say is that this is a pukka piece of kit. It does everything it needs to, and more in my opinion. Its robust and very well put together, like all of Microsoft's it's made to take a beating and still come back for more.
The size of the unit suits western europeans and not so much our asian counterparts, mainly due to the size of hand difference. The configuration of the buttons is something we are all used to now, so no surprises there.
In a nut shell, it's a great piece of kit that will do the job it's designed to do. To be fair, I like the MS range of gear that complements the xBox 360, so I don't have too many bad things to say about it!
Get one and it'll be the last controller you'll have to buy, as it'll last forever!!!!
