Buttkicker Gamer2, is it worth it?

[Kupsised]

+1 for this, I'd like to know as well if anyone has one. Still can't quite understand what it does mind, I've watched all the videos but still don't quite get it. Is it just a rumble pack, or does it act like some sort of sub-woofer through the viabrations?

Also, if someone does happen to have both one of those and the Obutto seat that'd be even better, since you can order one with the Obutto (which is why I'm interested), but some reviews I saw show that most gaming seats don't have the pole to fit the buttkicker on, so was just wondering if the Obutto has that or not, since I haven't got the patience, knowhow or time to fix one up if it doesn't have it.
