I lost 3 friends because we were in a situation where one of my assembled 510 mega's came up missing and it HAD to be one of them. We were enclosed in my truck the whole time.. I searched it high and low for hours. Conclusion... Can't trust any of them because one decides to have a brain fart. Sad really. These things are just that good the thief doesn't care that none of us can trust each other anymore. That's like loosing 3 friends over a measly 35 bucks.
