I just rented FAT2 (3.35 MH/S) for 72 hours, I'll report back after it finishes, it's working out great so far =)

edit: The rig had an hour outage, otherwise the hashrate is stable. Is it possible to get compansation for that? thanks!

edit2: I just got an extra hour! things are going great! 44:30 hours remaining

final edit: Everything worked out smoothly, the average hashrate on the pool was a little lower on the last day but it didn't show up on leaserig so I guess it's a configuration error. Excellent service!
