Are Zumacraft dies any good?

[Earstou]

I have a Cuttlebug I use occasionally, mostly for card making. I ran across Zumacraft slim dies today and was wondering if anyone has ever used them? They are only $3.99 and they are only good for paper, cardstock and vellum, but that's usually all I cut.
So I was wondering if anyone had experience with them?

I've never heard of them, off to Google!
