Absolutely perfect.
My main stick used to be a Hori RAP V3.SA, but after hearing about Qanba sticks and how they work with every system, I had to have one. I managed to snag one of these from Play-Asia for my birthday, and it's safe to say I'm in love.
The ice-blue motif is sleek and lovely to look at, and the design is safe from my sweaty hands under a thick piece of plexiglass that meets with the plastic case perfectly - can't feel the join. The USB cord is incredibly long and coils away safely into a small compartment on the stick side of the base. Sanwa joystick and buttons mean precision and reliability, and easy replacement should you want to mod with your personal preference of parts. Just unscrew the bottom and dig in. Speaking of the bottom, a cool feature is that it is lined with a felt material, which is a godsend for people like me who play with their stick in their lap. The felt grips onto my jeans and doesn't let the stick move an inch, regardless how "spirited" my playing gets.
I've had it for less than a month, but even so I can't recommend the Q4 enough. If you're on the fence, get off it - this is money well spent.
Oh, and it has a carry handle. A CARRY HANDLE. Come ON.
