Itach, sorry to say they're not worth it at all. They're good for some setups, I'll give them that, for example when I didn't have furniture in my apartment I had my gaming chair, 5.1 speakers setup to my 360 which was hooked up to my LCD projector. That was possibly the best setup for Ace Combat 6. I shit you not, I honestly thought I was a piloting an F-22.
So unless you're in a similiar position buy something that actually matches your living room set... not like my poor ugly red rocker. I'm going to go wish it well before I set it on fire.
