Proam jibs?

I'm looking into getting a Proam Jib. ( I've used one briefly on set, but not really enough to get a real feel for what they are like.

Curious as to anybody's thoughts on the products, is their life limited? Is it going to break after two years?

Also wondering if anybody has purchased one who isn't from the US and what dealings they had with that obstacle?

Cheers :)
