anyone try out Stinky Board?

I've been looking at various input devices to use with my oculus, so far I have a leap motion for the hand controls and I was looking at various locomotion systems, but then I found 'Stinky Board' (horrible name, for an interesting product).

I'm wondering if anyone has tried this out with oculus games, it seems like it would be great for VR games while sitting!
