Exactly the same here, an old friend I met up with a couple of weeks ago had one, after initially being sceptical despite the great reviews I was happily proven wrong by its performance. As you say though, if it were a real design I'd have one in a heartbeat. Even puts my old we g36 to shame and that was as good as anything else I'd seen at the time.
The first gen didn't have adjustable hops, I know that much. Only heard good about the newer ones though. I had someone on my team at a woodland game about 6 months ago with a full length AK thing (no idea of designation or anything) and it ran very well. Couldn't comment on range or accuracy though.
