How are you finding them Mic?
The thing that really ticks me off about PW is that they are laying the blame of problems with Canon and that Canon flashes produce RF interference.
Hello? PWs are a third party product supposed to work with existing Canon products - if they don't work as advertised it isn't Canon's fault. PW should have tested much more thoroughly and when the RF issue came to light should have modified their product to work as claimed.
It is hard to believe that they produced a product that works in certain situations. Makes you wonder if they had 20 580EXII that happens to be noiseless.
I would be going crazy over their testing/quality control department if this happened.

so I had to re-partition my storage drive, install Windows on that, downgrade the firmware, remove that partition, then install Windows.
