Eh, five screws and a battery swap apparently or send in your controller for a swap. I can do either so I'm not bothered but it'd been easier if there was a battery cover. Stupid Sony design.
Aren't you being a little generous with the 10% failure rate? At the peak of the RROD uproar it was ~30% from all sources not Microsoft and currently within the last few days the latest reports say failure rates are still possibly upwards of 16%.
