Anyone ever used an HKS BOV?

I'm talking about the SSQV. The one that looks like an overgrown bullet. It seems like these are of a good design. I might have access to a used one. (will find out the price tomorrow) And i can get a new one for just over 200 at the local speed shop. not bad considering some prices ive seen.

Anyone have any experience with these BOV's? so far ive heard from two people that they have had good luck with theirs. any other oppinions? critiques? flames?

Thanks,
