Original Xbox only.
Wireless, uses 2 AA batteries.
Sync isn't the problem as much as getting the sensors to recognize fast steps.

It works just fine; just isn't for heavy/expert play.

So yeah, who wants it? I'm not shipping it to you, you have to come get it in Seattle.
I have the first Ultramix for Xbox too, and will throw it in for $3-5.

(I also have a modded pump pad for original Xbox that I'd sell for $8-10 with Exceed for the Xbox)
