Zipfy Mini Luge: Anyone have one?

[jd83]

I am really leaning towards getting one of these for the kids for Christmas...They are total daredevils and absolutely love going sledding. Just wondering if anyone on here has one, and has an opinion on them? They have very good reviews on Amazon, so I'm hoping those reviews hold up.

I don't have one but they look fun.
