I love my folded crate... I use it all the time, for Flyball/Agility/Obedience and for traveling. It only weighs a few pounds (OMG my wire crate literally weighs 80 lbs) and it really is durable. I definitely recommend one, as long as it's well made.

When really, really excited at Flyball tournies, Gonzo has hamster-balled in the soft crate. But, only a few feet. C; And there's a plastic floor insert that can prevent that, for mine.
