Yep, that is the one, but that's the kinda lame-ish official Ubisoft one. Its design is top notch, but its functionality is not the best. I've seen some version on youtube that uses a ring to trigger the blade movement, so it works just the same as in the games, instead of using an awkwardly placed button.
As for cons, yeah, there was a time I went to cons, well two actually. Being a small country where there are only like 2 cons at all, and mostly in the western region where there are actually people who are into such things, for me it was too costly to travel to the capital city all the time, and to be honest, the first time I went I felt very good, like if I finally found my place to belong, but the second time, I felt the same thing as you. I felt that I still don't belong there, and in ways it was obvious, because there was only one person I knew from the group, the one who invited me, and it was a quite large group of friends, and I felt that I'm just intruder in their group. (That's also when I started seeing cosplay as something "not right". Like... dunno, how the clothes in animes look believable, but in real life, it looks all fakey. Or at least when it comes to anime cosplays, not western games.) I think a few months later I stopped talking to that friend as well, because both of us felt that we are too different to talk about anything. This happened with all of my friends in my life.
