If I was to get it I would use it on my BC and hand my primary off. I’d have to get a longer hose for the primary. I couldn’t expect someone else to know how to use that wasn’t familiar with it. As far as servicing it is much simpler than a standard second stage and is more dependable. The problem is the only one i’d know to service it would be the manufacture. (it should be checked every two years) I can not find much info other than the information put out by the company and I don’t know how old that is because nothing is dated.
I was hoping to find someone who has used it. If it is as good as it sounds why hasn’t it become more popular?
