Good but not enought for the price
the product is good but it's only a piece of metal with a Sanwa stick and Hori buttons and a big piece of empty plastic in order to add some volume and stability to the product.
it's true that if you change the square idler for an octogonal one and the hori buttons for some sanwas you got a really good stick but 150$ for the stick plus 150$ for the shipping and the duty (if you live in Europe that is what I paid) plus 45$ for changing the components...
In retrospect I think i should have buy a cheaper and more available stick and modded it the same way.

ultimate arcade stick (OOBE)
Seriously the best arcade stick around for xbox 360.
Robust arcade design with high quality components.

Bought 2 of the hori real arcade pro ex sticks and must say i really had a blast with my best friends playing SF IV after purchase.
This game was unplayable with other controllers for xbox.

Good joy-stick
it is useful for fighting!

Huge and fantastic !
Ideal for arcade party and retro gaming with the Xbox arcade Live catalog. Not for actual games using the left or the right original analogic stick.

One of the best out there
Very happy I bought this product, the stick feels great and the unit as a whole is the right size. It isn't perfect straight out of the box, like others have mentioned, a few modifications can change that, I'm replacing the buttons with clear semitsus and changing to an octagonal gate so I find circular motions easier to do.

Overall, if you're looking for the best stick for the 360 (other than the SFIV TE) this is for you, and modding it makes it feel like the genuine arcade experience at home.
