Opinions on Zone shocks?

I was going to order a set of the Fox IFP replacement shocks, but it'll be winter here soon, and I don't want them to get all trashed right off the bat. I've read some good things (there's not much out there) about ZONE's shocks... does anybody have some first-hand experience with them?

How did they ride?

Did they last long?

They're cheap enough I may just order them and see how it works out, but if they're absolutely terrible I won't waste my money.
