I have the OBX and the ball broke off but I just had it rewelded properly. It's all good now.
As for the Steeda, I have one I am about to put onto RyeLou's 98 CSVT and that thing has the same flawed weld design on the ball, so I wonder if that'll eventually break too.
I saw get the cheaper one and have it wwelded around the cicumference of the ball plate, before you install it, and you'll never have a problem.
