MS customer service is horrible. After a second xbox 360 unit was delivered to us to replace one that was fried due to "3 flashing red lights", this one also developed the same problem. To date, I have not been able successfully resolve this issue, and at this point, I have not heard back from MS after leaving both voicemail and email messages to get a date on when a replacement part would arrive.
The graphics on the games themeselves are great, and I was surprised to find myself addicted to Need for Speed Most Wanted. Before the 3 flashfign red light problem, which prompted MS to extend warranty protection on all consoles, the freezing of the games due to overheating was annoying at best. To solve the overheating/freezing issue, an aftermarket fan was purchased, which MS is now saying voided the warranty for the 3 flashing red lights.
