My reflow from the indy didn't take well the first time - they redid the work and it has been good ever since (2+ years now) - and this is an original 60Gb model I upgraded the HDD to a 320Gb - I play BF3 on it about 2-3 hours at a time - maybe 3-5 times a week... not exactly college kid 12+ hour BF3 sessions - but a good heating up quite often.
The guy who did ours has a proper reflow machine - a "Jovy RE-7500 Rework Station" - they do work on out of state machines - this is a pretty expensive machine for this kind of work, not some kid with a heat gun!
(and they guaranteed their work)

It's ALL perspective - get some. No - I am NOT addressing YOU!
