I dont get why some of the nerds on here would rather solder than screw in a mod chip, hell I would rather just plug in into a USB port if I could but I know they cant make them like that. Still anyone that would rather solder then screw in a screw is a retard, I dont get it, my friend has a Matrix and I had a Enigma, my Enigma screwed up my Xbox because of the "getting hot then cold" crap. And I got it professionally installed by a company around here, and his Matrix that he bought with a Refurb Xbox is working %100, he installed it himself, it came loose one time when his gf dropped his Xbox 3 ft, he took it apart put it back in very tight, never came loose sense, so I think i'll be buying a Matrix next.
